Personally, being an American secular man, I don't care. But I wonder if the women who wear them due to religious tradition really want to wear them or are forced to by the men in their culture, if that's the case then I am totally against the hijab.
I am an American and I expect visitors to respect my beliefs even tho they may not agree.If I am in a Muslim country. I may not agree what they wear but I must respect their culture. As for Muslims living in America and continuing their culture, I have no issue unless it interrupts our American agenda.
I guess an Australian viewpoint is valid, even though you asked about Americans.
While we respect the right of Muslim women to wear the hijab we recognise that it is an effective disguise and that any criminal (male or female) can dress as a woman and avoid identification while committing a crime.
Last year a woman, stopped for a driving offence, insisted that the police had tried to forcibly remove her hijab. They hadn't as was evidenced by their CCTV. The judge, who was a pretty smart guy, ruled that, under the law, police could not compel a woman to remove her hijab.
Why smart? Because within weeks a new law had been passed giving police the authority to make such a demand. Problem solved.
America is very diverse, not only in ethnicity, but also in religion and point of views. some areas are open-minded and respect the wearing of religious garb, other areas are not. i believe in the Christian religion, however, i am aware that my belief does not dictate the beliefs of another, and according to my belief it is never right to disparage another. respect, integrity, love and compassion are the behavioral cornerstones of most religions that i am aware of. i just wish more people of all religious and ethnic backgrounds would utilize those attributes more often.
The hijab is not a problem, Burkas & niquabs - fulll-face coverings) raise legitimate security issues, as Dodgy pointed out. A civil society cannot accept obscuring one's identity in any & all circumstances as a right. Women who wear these items will risk being increasingly isolated & marginalized in society - but perhaps that's the point.
I have no problem with people wearing whatever they wish- if it's their choice. My issue is when religions try to make clothing mandatory, especially when its sole purpose is to hide women away from society.
