"Blah blah blah blah blah, in my opinion, blah blah blah, so Federer is not the GOAT."
True, you should never get your hopes up. When you're driving, you assume everyone on the road is an idiot, in order to stay safe. When you post on an internet forum, you assume everyone is a child incapable of rational thought (to put it nicely), in order to stay sane.
Consider the set of all sets that have never been considered.
