The left thinks it's ok, because it's Canada. God forbid Trump do something like this (Because I'm principled, I'm anti deportations regardless). Don't expect the left to be principled though; they'll let Canada get away with xenephobic immigration policies.
They can deny it all they want; but at this point, I think I'd rather have them be honest and admit they're partisan hacks. Just come as advertised. Their mind won't be changed on this because they are emotional people and you can't reason with emotional people (even if they mask their emotion). Just come as advertised.
And if you're going to be emotional and unchangable in your views on Canada, then the internet isn't the right place for you. My mind is unchangable in the annexation of Canada, but I use logical points whereas it seems they don't.
If your brains are in fact emotional, then politics isn't for you as it would make you scared and that's bad for your mental health.
