I’ve always had a bone to pick with that expression.
What experience? If it’s an old fart with outdated views, yeah maybe they can keep complaining about shit that doesn’t matter anymore, but dumbshit people my age or younger? What experience?
It works better in context, the quote is "don't argue with idiots: they'll drag you down to their level, then beat you with experience." I've always taken that as "experience at being an idiot". The "yeah, well, muh wisdom/experience" copout is unrelated.
