True
I don't see much content from the extreme left, but why would I? Its not something I follow nor is it that much an issue. When it happens, those on the left do get banned/suspended, as do those on the right, but it's the right moaning about just their voices being blocked, when it's only the voice of those that are extreme on the right that are suspended.
What I see from the left (in America) is what comes from the guy in charge, and that is what I listed as a left thing. There are also extremes to the right, but the right doesn't seem to have a position these days that aren't extreme. You've mentioned what the left also want, but didn't refute any of the points I made about what the right talk about, nor what I wrote about the jk Rowling bit in reply to the daft comment the user I was quoting had wrote.
