Gonna be fair and give him the benefit of the doubt because he might be still in denial. Nobody likes to think that the friend they knew for years is a degenerate. It's easier to believe that he's just living his "true self" and that he's harming no one. Even those inappropriate jokes he could have said were probably jokes for when they were in private. "Why yes, I masturbate to anime porn? Who doesn't!" sounds like a sarcastic joke.
Of course, we all know troons are loose cannons and this one is going to blow up at any moment. I mean, first week of being a troon and he was already grooming the child.
The real test will come when Chris does something really inappropriate. Because Beast knows well he needs "let go" his friend, but the people he works with and for will try to tell him it's all lies by the evil conservative MAGA nazis who won't let true and honest transwomen to have abortions no matter how much he insists he's also seen the evidence of his former friend being a pedophile.
