Harper was worse than Bush Jr. imo, if the barriers placed by Chretien and Martin weren't put into place, Harper would have done far more damage. Like for starters he wanted to repeal same sex marriage, which can't be done. Also Harper has resorted to dog whistle racism and fascism, not just targeting Muslims, but with his hateful C-24 law (which is going to get repealed and throw out to the trash when Justin and the LPC come in), he basically turned a huge chunk of Canadians into second class citizens, regardless of their background or if they were even born in Canada.
Canada isn't known for this kind of fear mongering, so people didn't pay attention to Harper, but his tenure was basically the lost decade for Canada.
Fuck, I mean Dubbya wasn't even like that to Muslims, but the Saudis were his masters, so eh.
