Or is it that they don't want their bullshit to be censored off the face of the planet? Whether or not we agree with their views, should they not be able to express themselves, and how they truly feel?
Imagine if your criticism of their viewpoints was being censored instead, so they got to speak un-opposed and un-criticized.
I constantly hear that people should "be themselves", and "should not be made ashamed of who they are". It appears this advice falls down when the people aren't who we want them to be, or hold views we consider "wrong".
If I hate a specific ethnic group, how else do you expect me to change, if not through sharing my views and then being challenged on those views. If you censor such a person, would you not then further radicalize them?
