I think it's because of the different movements it has been associated with in the past. I don't hate the women who wear them, but I can't deny that the visual has some negative associations in my head, as much as I may try to counter them. Usually I feel more curious than anything when I see it. 

I don't get it. What do they do? Scream and start crying, begging for their life?

and >99% of people don't "hate" you. I don't know why you'd ever get that idea. It takes more than some stuff on your head to make someone hate you, unless it happens to have a swastika painted on it.

Because, regardless of what people claim, people only accept what they want to accept. 

Right now it's really popular to accept people that have no firm standing-- so typically people with firm beliefs are often called radicals. Many who exhibit that kind of clothing would be considered radical...

It may not be so much the veil itself as the woman wearing it.

There are Jewish women who cover their
heads. Christian women who cover their heads. Messianic women who
cover. Muslim women who cover...etc.

I can not speak for all women who cover on why they cover.

I can give a few of the reasons

1 cor 11 in the bible

There are verses in the Koran

fulfilling
a mitzvah (commandment) that is founded on tzniut (modesty), the most
important characteristic of the Bat Yisrael (Daughter of Israel).

A
woman completes her attire with head-wear that is impressive in its
refinement, and reflects the regal and virtuous character of N'shei
Yisrael (Women of Israel). (Mekorot 32:1)

"Strength lies in conforming with the ordinances of the Torah" (Shir HaShirim Rabbah 2:10).

And
say to the faithful women to lower their gazes, and to guard their
private parts, and not to display their beauty except what is apparent
of it, and to extend their headcoverings (khimars) to cover their
bosoms (jaybs), and not to display their beauty except to their
husbands, or their fathers, or their husband's fathers, or their sons,
or their husband's sons, or their brothers, or their brothers' sons, or
their sisters' sons, or their womenfolk, or what their right hands rule
(slaves), or the followers from the men who do not feel sexual desire,
or the small children to whom the nakedness of women is not apparent,
and not to strike their feet (on the ground) so as to make known what
they hide of their adornments. And turn in repentance to Allah
together, O you the faithful, in order that you are successful
Surah an-Nur ayah 31

O
Prophet! Say to your wives and your daughters and the women of the
faithful to draw their outergarments (jilbabs) close around themselves;
that is better that they will be recognized and not annoyed. And God is
ever Forgiving, Gentle.
Surah al-Ahzab ayah 59

@HLPU@xanga - actually many women who veil...Cover their Hair...not the face. Expression can still be seen

subsacred.xanga   got it right. Those are most of the feelings that are elicited by the public in the United States when they see a veiled woman. Makes you look subserviant, second class.  And it can make you look like an attention whore.  Especially when you assume others are "frightened" by your appearance. If that is true, why would you continue to wear a headgarment?

As I recall, you believe in the Bible. Isn't there a passage somewhere that says to not do things that cause other believers to stumble? To insist wearing a veil is the correct thing to do in the presence of new believers causes them conflict, confuses them.

You really want others to believe you are somehow more "holy" by wearing a veil? Then you miss the entire point of Jesus' message in the New Testament. He tried to teach everyone to look beyond the technical aspects of keeping the "law". That is what the Pharisees did, and He ridiculed them all the time. They stood on the streetcorners and loudly preached their long, pious prayers, they flaggellated themselves, they made a big show of themselves in Temple to make themselves look good in mans eyes, all the while corrupt in God's eyes.

Jesus taught that what comes out of a persons mouth and heart is what matters. Who you are, not what you look like. What you say and do, not appearances. 

It is sad how so many people cannot see the forrest for the trees...

It's not hate.

It's pity.

You have let something we consider a work of fiction to rob you of your very appearance.

This isn't an attack.  Just a to-the-point response to your question.

I don't think that it's hate. The whole idea of covering the head just seems so archaic. Yes in one of the chapters in Corinthian Paul did mention that a woman head should be covered, but it also that a woman should be silent in the church and that there salvation is through child bearing and so worth. I think sometimes the thing that are written in the bible are not meant to be taken literally. I think the whole idea of head covering, and outside appearance does not have anything to do with a person's salvation. When I see someone with their heads covered I think of Matthew 23, where Jesus was warning the Pharisees about being too focus and on outward appearance and rules made by man, but were not really folowing the word.

@sierrraa@xanga - If you would read my blog you would see that not every post I write is about veiling. Even if you read every post that Revelife has used of mine not every post is about veiling. Only 2 of them even mention veiling....That is in no way even close to "Every one"

i think it has a lot to do with fear of something different and unknown. and it depends what kind of veil or head covering you're talking about, as well. no one i know of sees a nun and says, "those damn nuns, they're ruining the country." but i know several people who see women with a middle-eastern appearance and traditional clothing and something inside them snaps and they feel the need to announce to those around them that "those damn muslims are taking over the country, and they're going to impose islamic law on all of us and bring on the apocolypse," as if they take it for granted that they're speaking for everyone present, that it's just a fact that no one can dispute. but nuns are christian, and in the minds of many christian men, christian women must be submissive and quiet and obedient. i think nuns and other kinds of veiled christian women aren't really threatening to american christians in general, just different. you just look at them and think, i wonder what sect or denomination or religion she follows. the religious right sees a muslim woman and red alerts go off in their brains.
