Super-late comment, but I agree! Sheldon can be really rude and inconsiderate to his friends, but it seems like the show only ever focuses on calling him out for that, and doesn't recognise the way that they can dismiss Sheldon's feelings which are just as legitimate to him. And honestly I just thought what an idiot Leonard was being, so it was hard for me to take his discomfort seriously when he could have easily just acknowledged that things like that do bother Sheldon and itch at him, instead of getting all competitive over wanting to prove a point

Penny apologising this season for dismissing Sheldon's feelings felt really unusual actually, the show normally just laugh's at OCD Sheldon and his quirks and rarely treats his feelings as legitimate and real for him. And then even that scene ends on Penny insisting on a hug over a handshake, which is played as cute, even though we know that Sheldon has a germ phobia and really doesn't care for that kind of physical contact
