Some of the things in that comic aren't even sexist. A guy sitting with his legs wide? Yeah, that's rude, but it's not because he's a guy, it's because he's inconsiderate. I've routinely had to step off of the path when walking to class in order to let a group of women pass because they were taking up the entire walkway, oblivious to those around them. There are people of all genders (and all races) who are inconsiderate of how much space they take up in public, and it has nothing to do with their demographics.
EDIT: Also, as a guy who has been told by complete strangers that he should cheer up, smile, or otherwise not look depressed in public, it's not a gender thing. Well, it is, because I'm sure women hear it more, but that's because society teaches us that it's acceptable to care about random women, but to fear random men. It's a problem that we think we can tell random people to smile, and it's a problem that happens more to women, but it's not because they're women that we think they should smile.
