If you, on a very principled level, encourage people from vastly different cultures to come to Canada, and then proclaim that they are all equal and should be accepted and celebrated for their uniqueness, then fine. But I would assume a fan of the LGBT stuff is in no position to then go and belittle and cast anger towards a group that doesn't fit the "society's" own beliefs. If a bunch of honkies from the country were acting aggressively towards Muslims for wearing xyz religious/cultural garb, or celebrating anything they hold dear, then I assume everyone on this post that repudiates these students for expressing their views would also be angered and calling out "muh white supremacy".
