In Holland the law is quite clear about it, see below quote:
So, in Holland she should not wear a nikab when on public transport
Of course it's absurd to bully someone. Just remind them politely is sufficient
I don't know what the rules are in Norway. If there is no law against it, then the man clearly has big issues
And I don't get it, those Muslimas look so nice with a Nikab. I find no problem, if they like to wear it
I only once met a very bad Muslima, threatening me "you Dutchmen are weak, in 20 years we have taken over Holland"
But that is already 35 years ago, so she was obviously very bad in fortune telling also
