One of the things that has sadly left me feeling a bit estranged from the Left over the last year is realizing exactly how many people of that political persuasion are just as comfortable throwing away the rights of people they just don't like as much as the Right can be.
A free, liberal democracy only works when you protect the rights of the contemptible as well as the noble. If you open the door to censoring things based on your tastes you legitimize that tactic against yourself down the road. And there is no real defense when you deem arbitrary bulls**t subjective tastes fair game as a justification.
What's terrible is that this type of "leftism" is spreading in popularity in College campuses in America. These people are an illiberal authoritarian cult with a Leninist mentality and it's insane. Think about College "SJW's". It doesn't take a rocket scientist to see that if these people had any real power the "re-education" camps would be setting up from day one of them taking power. They would establish a police state monitoring people's every phrase and, if they could, thought. Freedom of speech and expression would be things of the past. And they would seriously believe they were making the world a better place the whole time. It's the True Believers you really have to watch out for.
