A reddit forum called r/facepalm full of staunch leftists with "the left does no harm; saying both sides is a strawman argument when it's clearly the right who have gone clinically insane" cognitive dissonance, and we're expecting any nuance or truth to be discussed there?

I saw a guy in the comments section likening grooming in schools to teachers simply "sharing their opinions". There is no reasoning or dealing logically with these people.
