PS is actually extremely insecure and it's showing in his videos.
Listen to his halting expression and his higher vocal tone. He speaks as if he's hiding something, and he is hiding his insecurity.
I have nothing personal against the guy as I've never personally engaged him, though it would be interesting to do so. I just remember reading a bunch of angry, somewhat condescending posts from him and I've seen a few videos in which he personally calls out members.
He cares way too much, and that is the core of insecurity. You can actually see it leaking out in his vids these days.
