This is a complex issue.  As a western woman and a feminist I don't like the niquab but I don't like the idea of the government telling anyone what to wear.  I also think it depends on the public circumstances.  Niquabis should be able to ride the bus.  If the woman behind the counter at the MT O wants to wear a niquab, I might not like it, but it doesn't really affect me.  If my daughter's teacher wears a niquab, I would have a problem with that.
