For the record, while I'm not actually aware of the racism though I find it believable, the transphobia isn't really hidden.

In the book he's excerpting from he goes into even further and more overt detail in the broader transphobic rant - his general opinion seems to be a rehash of the old 'homosexuality is bourgiese decadence' thing, but applied to being transgender instead.
It's really quite obvious and heinous in the book, there's even a moment where the conceptual connection is made clear and he went so far as to plausibly-deniably imply that being homosexual should still be considered a mental illness.
The O9A as far as I'm aware has zero FBI connections originally, it was started by a genuine Nazi occultist British crank.
What you're thinking of is the Tempel Ov Blood (Yes that's how it's spelled) which is essentially the American denomination of the O9A who have their own modified version of the theology and all that shit.
The founder of that IS a known FBI informant, though I believe he became an informant after founding the TOB.
I unfortunately know a lot about these groups.
764 is technically a separate group that's really just in it for the pedophilia, little Epsteins, but in practice there is A LOT of overlap.
