If you're interested in more memestock material, the man spouting merger conspiracy theories at two Gamestop employees in this video is the subject of an entire video by another creator, which Dan Olson retweeted. I'll warn you, this other video is also funny but much more disturbing. It reminds me of watching Terry Davis's vlog posts as he suffered from schizophrenia, it's definitely more uncomfortable and tragic.
I fear that guys like this will turn to "Forcing The End" as other conspiracy/apocalyptic/cultish groups tend to do.
