Men go to the gym for themselves and secondarily, because it raises their attractiveness and confidence in front of everyone, not just women. They chat up strangers at bus stops, because dating is a literal lottery for the guy.
Your second paragraph is true, but it's not related to entitlement.
When a man chats up women at a bus stop it's because he likes women and wants to date them, obviously; when he yells "fucking whore, you think your too good for me" after getting turned down it's because of entitlement, and part of the reason he feels entitled is that he put in effort to make the first move.
