It is a core part of leftist ideology that any ideological dissidents should be incarcerated if not outright exterminated.
There are a lot of posts in threads on DU that say exactly this. I've also had a Republican candidate come to my door campaigning and tell me that one lib she met said "All Republicans ought to be in jail".
I say, "Come in and get me, copper".
Amazing how honest some of them are.
Make no mistake, they ALL think this way, to some degree, that the government should be used to punish those who don’t think right.
