I think most of what gets lumped into “PC” is silly and counter productive. I think the neo-nazi movements are awful. I think Sharia law is incompatible with a modern society. But as a defender of free speech, I’m not going to support silencing people who belive silly, awful or abhorrent things. If free speech covers your right to be offensive, it covers the right of people to say “I am offened”. If it covers your right to complain about PC culture, it covers the right of the most walking on eggshells-exaggerated-straw-man-SJW to call you problematic.
If SJWs have lack a right to “not be offended” then you have no right to “not be offended” by SJW silliness.
