I've seen quite a few posts on here placing the responsibility for gender ideology catching on on a combo of misogynistic & influential autogynephiles, and gay & straight men who backed them up.
I definitely think the core of the TRA movement is misogynistic men. But we also need to try & work out why several feminists promoted this stuff. After all, Butler's Gender Trouble is the Bible of this.
It's notable that supporting gender ideology and supporting paedophilia seem to correlate. Gayle Rubin is a notable influence, as is the now Patrick Califia. Both wrote in the 80s that child-adult 'sexual contact' could be OK.
