Regarding the “I can say what I want because everybody’s so PC these days and always offended.” argument, I offer you tact.
Once you take off the shields and the boxing gloves and realize not everybody plays in the sandbox of “offended / no offended”, there’s a whole new world of intellectual stimulation that includes such things as tact and diplomacy built-in. If someone is offended, it no longer matters: you address their points, not their offense. In fact, it becomes a situation where you don’t don’t see them as ‘offended': you see them as rational beings with points to make and you address those points rationally.
It’s freedom. Learning tact means you can now talk to everybody about anything.
You may disagree. You didn’t ask me to be your Aunt Mabel. But take it as you like.
