Where is the limit to any government dictating women's garb? Is it just burqua?
The government already sets limits on how people are permitted to present in public - that's why you're not allowed to stroll around the streets naked.
WRT to other dress, I think the limit should be burqa/other face coverings, yes. This isn't about wanting to restrict religious freedom or freedom of expression. It's based on the same principle that says it's not OK to get about in public with your genitals out - covering one's face violates social norms, can present a security risk, and creeps everyone else out, to put it bluntly. That isn't because of prejudice against Muslims. It's because of deeply rooted evolved instincts around how we recognise, assess and relate to one another as human animals.
The reason we feel instinctively creeped out when we see a faceless person (whether they are wearing a burqa or a balaclava) is because the face is so basic and fundamental to human social interaction and risk assessment.
