Frankly I'd welcome deportation of Canadians from the U.S.; they are a huge source of radical liberalism in this country.
And no, I don't want them becoming citizens. If we do that maybe we should merge with China too while we're at it. No good could come from that.
But of course this isn't what they are talking about. They are, rather, fighting a straw man, demanding ICE not make raids inside of their own Canadian cities, as if we ever had done that or ever would. It's pure political grand-standing.
Make you guys a deal; we won't raid Canadian territory if you promise to stay in your own country and quit exporting your loonie ideas to ours. Live and let live.
