Other than noting that Doomsought wants:
You gotta take his linking of LGBT's and pedos with a grain of salt.
Let's look at the history of gays and pedos. Some useful studies, done before gay rights was in its ascendancy, show us that the majority of pedos, even man on boy pedos, aren't gay when it comes to their adult preferences, instead just having a fetish for children, and have access to boys (hence why the catholic priests molested young boys, not girls). That's not to say gays are never pedos, just that the rate for adult gay men is similarish to adult straight men (I don't recall the exact breakdown, and I'll look up the relevant studies if you want, I just don't feel like tracking the down in my posting history right now.)
As for NAMBLA, yes, it absolutely tried to get on the LGBT train. Why? Because for them, they want acceptance for their evil. Its the same reason the KKK protests the Westboro Baptist Church (yes, this happened, it was kinda funny). It was founded in December 1978, and immediately tried to join up in gay parades. A few people were so blinded by politics that they supported it, but many organizations were immediately against it, notably the lesbian ones. It relatively quickly became politically isolated even in the gay community. Basically, look at them the same way one would look at an obvious actual racist trying to join a normal conservative protest, only worse. They are 'joiners'.
And they are trying to join again, and succeeding, because they put a small veil of 'not technically' over what they do (e.g. drag queen story hour).
Now independent of this, a bunch of historical gays also had sex with teenagers (no I don't mean 18 or 19 or even 17). This is wrong. It's also mostly stopped (down to a level similar to straights, I'd guess). It happened because gays lived in a moral desert pre-Stonewall, where they were conditioned by the police that every sin was equal, as just kissing a guy had a similar result to living with a 15 year old: prison/uber cancelled (lose job, lease, mortgage, etc as your name was published in the paper as a gay), and get caught twice lobotomy or castration, your choice. As this has ended, we can watch the gay community basically normalize as gay 'culture' dies. From constant sex in cargo containers to committed relationships with cheating, to actual families without cheating. It's been a huge improvement in morality. Until the past five years, it's all been positive.
