If someone, say, from the Game of Thrones cast would openly say "fucking ni**ger" to another person while on air, he'd be done. In gaming culture, fans run to his rescue.
Again, I'm not trying to be flippant, but I don't see how the current culture in "gaming" isn't hostile, and for now I'll stand by my point from earlier. You're far from being wrong, I'm agreeing with what you said. However I don't think it negates my point.
If someone from GoT said that, their bosses would make sure they're done. They'd still have defenders online and in conversation. PDP's boss in this case are his sponsors and Youtube.
