Phil says he was talking to Mike recently and Mike asked him what he thought about Mutahar disliking him.
Phil said, 'I don't even know who that is. Who is that?' and Mike told him, 'Oh he's that YouTube channel SomeOrdinaryGamers.'
Phil claims he responded, 'Yeah, I don't know who that is. So, wait. You're telling me there's entire communities of people based around hating me and I don't even know them?'
Yes, Phil. A guy who periodically mentions you as an example of a pathetically laughable fuckup of a loser means that his entire existence revolves around you and everyone he's in contact with is for the purpose if coordinating negativity against you.
Phil can't talk to someone for 5 minutes without dropping overt signs that he's a delusional narcissist. New information that there's a guy who doesn't like him gets instantly turned into a conspiracy about a shadowy new group of people out to get him.
This was given as an example of why he was smart not to do the documentary because Mike was talking to people that Phil wasn't even aware of, so how could he possibly assess the negativity it would cause?
Phil the Shut-in acts like it's some revelation that people are aware of him that he isn't and they don't like him.
