See William Banks.
I highly doubt that Alefantis would at this point with everyone watching him, engage with some random PizzaGate T Shirt salesman and threaten him. Why have I not heard from Alefantis? Why hasn't anyone else but this one dude who just appeared on YouTube when this situation started.
I am sorry but this Ryan kid and I have discussed this with a few other big time YouTubers who have interacted with him is lying. He refuses to produce the evidence to multiple other YouTubers but wants us all to cover "his story" of being threatened. Trust me he acts super shady when you start questioning him. Just go do it yourself and you will see.
I am calling BS on this kid and I have not seen one single shred of evidence to the contrary. Mixing truth with lies intentionally to sell T-Shirts and get your 5 mins of fame is pathetic.
