dude: *does depressed edge-lord shit, is a perpetual contrarian even when he's clearly wrong, acts like a douche to writers claiming he knows their own universe better than they do even when he doesn't, mocks LGBTQIA-related fics because of course "OPINIONS" - his Twitter's even worse*
everyone else: *reacts negatively*
dude:

this dude named Late_Night, you've probably seen him all over the comments during the pride month fics shitting things up and just generally acting like a twat and moping about how everyone hates him when he gets called out on it

Ah, I guess I'm lucky I haven't; I don't really venture outside my comfort zone of my homepage and seeing followed people's blogs. XD

He's at it again. Someone posted a story, the guy started bashing it because it had an Applejack x Rainbow Dash pairing and acts like anyone who supports it is a complete idiot.

He's back and just as bad as ever.
