Well, we are. You haven't been reading threads about how we - and all the other Western nations - signed the UN Convention on Refugees in 1948 and committed themselves to taking refugees. This was after 6,000,000 Jews died because no Western country would accept them in the 1930's.
One screwed-up shithead kills a girl and ALL Muslims should be banned from Canada because "they're all like that. It's in their Culture". Do you actually listen to what you write? There are a million Muslims in Canada who DON'T do what this guy did. But somehow "they're all like that".
So you're going to ban them all and withdraw from the Charter? Canada would be the ONLY Western country to do that. You want that?
Oh btw, those Pakistani IT guys you go drinking with every weekend who you think secretly hate you? You any idea why that would be?
