Not sure what "cult" you are referring to but Islam and transactivism have in common an appalling attitude towards and treatment of apostates.
There are extreme examples, such as that of Salman Rushdie who has had a Fatwa to kill him since publishing The Satanic Verses in 1989. in 1991 Hitoshi Igarashi, the Japanese translator of The Satanic Verses was assassinated as part of the Fatwa. Rushdie has needed constant close security and survived being stabbed in 2022.
Less extreme, Lubna Zaidi has had to leave her home town of Luton and go into hiding due to credible death and rape threats to her and her children from other Muslims. This was because she dared to call out the "bad apples" in the Muslim "community" in the UK.
The Sceptic | Episode 47: The British-Pakistani Woman Getting Death Threats for Calling Out Rape Gangs, Migrant “Sanctuary Cities” and Debating a Green Loon

Similarly, Philippa received death threats and had to leave London and then Norwich after questioning the holy creed of trans.
By contrast, on the very rare occasions when someone with gender critical / sex realist views has a brain fart and goes all TWAW, the reaction might be disappointment but it is not some sort of TERF Fatwa.
No death threats, no rape threats, no telling people to kill themselves, no denouncing people to their employers, no trashing businesses with fake reviews, no harassing their families, partners and friends, etc. etc.
It is not gender critical / sex realists who display cult-like behaviour.
