Ya know, they probably put the "But you're a girl! Leave it all to the boys, and get us coffee/sex!" in not for the sake of making Super Girl look better, rather to show that there's actually people like that, and help show that that BS is not all that popular. Makes them look like jerks, villains, etc. and that's more the point.
Coz,lets be real, that mentality is alive, and well, and it's part of the reason women are a minority in medias. There are guys that hate women for being women. When these people that look down at Super Girl (Almost wrote power girl. Don't I wish. <.<) change their tune, and be more tolerable, it might send a message to the people with that mentality. they don't have to change, but i we generate more acceptance, then it's better than none.
The reason the gendered derrogatory speech sounds stupid is largely because it is stupid, and some people need to understand that more than others.
Womenstill have to fight for acceptance in areas of the world, and there's nothing wrong with highlighting it, imo.
