Correction, this is something NAMBLA labeled themselves, they are not part of the actual LGBTQ community in any way, shape, or form. At least they weren’t allowed until now, clueless progressives sure left the door wide open for them with this Notsexual™ crossdressing child stripper bullshit.
Complete nonsense. NAMBLA were literally the first American member organisation of International Lesbian, Gay, Bisexual, Trans and Intersex Association. They remained so until 1994, due to outside pressure, when ILGA received consultative UN status, and congress passed a resolution prohibiting UN funds to organisations advocating pedophilia, all because one Republican politician stirred up a storm. NAMBLA also used to dominate the committe that organized NY Pride in the 80s, and were a huge presence in SF and NY Pride.
And ILGA themselves used to advocate against age of consent laws until the mid-90s, when they reluctantly had to purge the pedophiles to go mainstream without putting off the normies too bad. A mere couple of years later they decided to advocate for gay parenting instead.
And the same was true for any sexually liberal, LGBT progressive country. The Netherlands had their own ILGA member pedophile organization.
In Sweden, the premier LGBT organization par none, RFSL, had their own pedophile "work group". One of it's founder is hailed as an LGBT rights pioneer, and was key note speaker at Pride event a few years, still being an open advocate for pedophilia, even lamenting in an interview that there's no place such public discourse anymore. I'm sure he would have gotten along great with another gay rights icon, Larry Brinkin (with his very own week in SF!), the architect of gay domestic partnership that would later devolve into gay marriage. Now in prison for possession of CP. Who da ever thunk?
An Interpool investigation in the 90s also found that RFSL's "travel guide" was being used as a guide for pedophiles in South East Asia.
In Germany, pedophile interests groups wielded political influence via the Green Party in the 80s. Literally conducted public discourse like it was nothing.
In UK, PIE, the Pedophile Information Exchange, literally received government funding, and were directly affiliated to the National Council for Civil Liberties.
And you'll find dozens of such group all over the world, all intimately affiliated with the modern, emerging gay right movement.
So no, NAMBLA doesn't just claim to be a part of the LGBT movement, they were a deeply ingrained, important, influential part of the LGBT movement. And what we're seeing now is not a slippery slope, it's back to baseline.
