Why did Outlaw delete the threads?
I'm not sure, they haven't said, but if I were to guess -
1) One of the threads went bad with a few calling him a freak, and others making passive - aggressive comments sorta like paraphrased - "I'm glad he's happy, but if we accept this, then what about pedophilia, bestiality, etc....?".
2) Maybe he second guessed having it out there because it spread to other boards super fast.
