I've included a link to the video. There are some other questionable things but this one seems the most unfounded and sort of out of nowhere. I wonder If Coulter just knows she can make money off controversy. I really don't follow the argument that people shouldn't be allowed to wear Hijabs or that that some how means they aren't assimilated to american culture. Firstly because american culture in so nebulous and secondly because I don't see how it differs from someone who (by their own choice) wears a Yarmulke, saint icon, vestments, cross, turban, ect.
I guess my sense of what makes an american isn't threatened by someone in a hijab or a turban. It's fairly common to see women in hijabs where I live and they're just link anyone else. Driving around, walking with friends, shopping with their kids. I don't feel like they aren't assimilated.
Personally the idea that people would have to be stripped of their cultures when coming to america is sad and scary to me. I wrote a paper in high school once about visiting three houses in a weekend. One was the home of a catholic family who weren't recent immigrants, a first generation greek family and an Indian family. I thought is was beautiful how in each home they had their own little religious spaces with icons and other objects from their cultures. It would make me very sad if those people had to give that up to be American, especially since I didn't think any of them were really much less american than me.
