Lefty pronouns are almost a bottomless pit of absurdity. "They" isn't a proper singular pronoun for a known individual. "Xe" and "Xer" aren't even words. Making a pronoun that is absolutely, completely, obviously and totally unworkable is the only way to troll, because anything less could be serious. The exception would be if you're playing at being one of them, but I'm guessing that the motivation for this was closer to "this is very very dumb and I want everyone to know I think it's dumb."
