He is better than the vast majority of MMA fans and much smarter than most of the people that hate him. He's just not as smart as he thinks he is. He swims in the cesspool of idiocy that is the MMA fandom and media, so it's hard to blame him too much for being abrasive.
The problem with retards is that they also demand to be coddled like little children. The mentality is "I'll act like a complete spastic, but if anyone ever calls me a spastic, my feelings will get hurt and I'll accuse that person of being of being arrogant." And it's exhausting to pretend that these people aren't retards. That's why so many people hate Luke Thomas.
I hate Luke Thomas when he's being a dipshit. A lot of people hate him when he's right, because they are dipshits. That's the difference.
