If you’re a frequent rider of public transportation, you’ve likely got a long and carefully detailed list of pet peeves and grievances. (See NewsFeed’s own list of punishable subway behaviors here.) Now, some of these pet peeves may be pretty specialized, but chances are we can all agree on at least one general principle: people need to stop taking up so much space. Or, more specifically, men need to stop taking up so much space, according to a new Tumblr that documents this problematic phenomenon.

“Men Taking Up Too Much Space On The Train” collects photographs of what the site’s curator deems “a classic among public assertions of privilege.” As the Huffington Post points out, “the men photographed in this Tumblr aren’t doing anything malicious, but it’s an interesting visual representation of the way that men feel totally empowered to take up a lot of public space — and women often do not.”

Commentary about male privilege and gender roles in society aside, the Tumblr is mostly just a funny way to do a little public shaming. Like this guy: do you really need that much space, sir? Probably not.
