When was the last time you met a reasonably attractive girl IRL who wasn’t getting attention from half a dozen guys angling to fuck her

One of the earliest rules you learn is that if she is single, that's a red flag in and of itself.

Also acknowledging that women are constantly drowning in attention they don't even appreciate wouldn't go over well with most guys. Its one of those "everyone knows it but don't dare mention it" things, because it would turn a lot of men misogynistic and hateful quick to compare their "still obsessing over being called handsome 6 years ago" lives.
