Last I read the bomber’s widow was an American and converted to Islam. I think that cuts the legs out from under immigrants not assimilating.
I’m not so concerned about the wife doing the hijab thing, as maybe being a clueless idiot dominated by a murdering asshole husband. The dead husband’s mother sounds like a batshit nuts fundamentalist delighted her son had a timid dolt for a wife. That bugs me, too.
OTOH, Coulter bugs me a lot because she’s unfailingly awful.
