Oh, dealing with dumb fucks on the internet, huh? Well, there's no shortage of them, that's for sure. The most mature way to handle them is simply to ignore them. Don't waste your time engaging in pointless arguments or trying to reason with someone who clearly lacks the capacity for rational thought. Just move on and focus on more productive things. Trust me, there are better ways to spend your time than getting caught up in the stupidity of others.
