To be fair, even if the vast majority of gay men very rightly hate pedos, there are a disturbing amount of them that will try to downplay the existence of the gay pedos that do exist simply because it reflects poorly on their in-group. The same is true to an extent for everyone, hence the copes of "actually, Trump was just getting close to Epstein to investigate the pedo ring from the inside, trust the plqn" or "actually, that tranny was just pretending to be trans to touch little girls, he isn't actually one of us." No one wants to admit when one of their in-group is a diddler, it's understandably uncomfortable to have something in common with somebody who'd do something like that, but too many people will then try to bend over backwards to explain why 'the pedo actually isn't one of ours guys I swear' simply because they have the same sexuality/genderwhatever and want to save face, and unfortunately this kind of behavior seems to be particularly prevalent in the lgbt community.
There have been a lot of times when I've shared a very extremely bad experience from my childhood with a gay man, telling past partners or close friends of mine, and it was absolutely sickening how many of them reacted. Lots of them would give some variation of "he probably was actually straight" or "his actions were caused by minority stress, not homosexuality" "you should be careful of who you tell about that" or "you've been brainwashed by Christianity/republicans/whatever into letting that color your perspective on the lgbt community." Basically, always a focus on how the "community" looks because of it, due to the fact they feel some misplaced sense of kinship for this guy simply because they both like cock.
I will say, it's at least slightly better than the troon approach. Whereas the gay men I've talked to go "well he's not really gay/not all gay men are like that" in response, the trannies tend to be totally mental and say "it didn't happen/if it did happen it's not that bad," so credit where credit's due, I suppose.
Maybe it's something like a response to the "all gay men are pedos" alarmism from a whole back. Where a lot of the crazies are so desperate to counter that argument that they've gone to the other extreme and began declaring the opposite: "no gay men are pedos," so by their logic, if a gay man molests a child, he must be straight.
Obviously not all gay men touch kids. The overwhelming majority of them don't. The issue I have is how many will hear about that happening and their first instinct is to turn it into an optics game (and yes, I know gays are far from the only group to do this) but it's all so tiring.
