ok, so, as far as i can tell, there's actually not a reason they can't remove their turban - like the hijab, it's really just a fashion decision.
what i already knew was all that there apparently is to know - that it's one of their "articles of faith" and that it's worn as an identity marker.
so, sikhs wear turbans because they're sikhs, and sikhs wear turbans.
that's fine and everything, so long as you're not going through a security screen, in which case that's simply not a valid argument.
it's not like they've been told they're going to go to hell or be excommunicated or something. it's just something they do because they want to, and because it makes them feel a part of a club. surely, removing the item from one's head for a few moments doesn't expel anybody from this club.
so, what's underlying the refusal, then, really isn't any religious significance, but rather just a trivial ethnic norm. and, that consequently isn't even a question of religious freedom, whatever you happen to think about it.
it would be one thing if somebody ripped it off his head and played soccer with it in front of him. that would be rude. but, everybody needs to go through some inconvenience, sometimes, to ensure we're all kept safe.
the real issue here is that navdeep bains appears to be a remarkably arrogant person that thinks he's special and deserves special treatment. he doesn't want to sacrifice for the team.
i repeat: i would like to see him defeated in the next election.
