Identity politics were and are still at the very heart of the Conservative party. They're doing it today in their leadership race  and did it for 10 years while they were in power. Harper hated Muslims, could have cared less about our indigenous people, differentiated immigrants through the use of terms like "old stock" etc.  The list goes on.  If you're going to call Liberals on this (and I'm not arguing with you that you shouldn't), then call the Conservatives on it as well.
