Not a radical feminist, but

The narrative-assumption is that only radfems oppose the religion of Genderism, sure. While I'm not strictly a radfem, I agree with many (if not all) of their viewpoints and arguments in that of the pejoratively-called "grievance studies", I believe that (2nd/4th-wave) feminists are the only such discipline that have objective, un-refutable concerns.

That being said, although radfems are the boogyman (*boogywoman) of choice for TRAs, its a farce to believe that criticism (or outright detraction) of gender ideology need necessarily come from a radfem perspective, and I think we've seen that perspective become more widely-acknowledged in radfem-GC circles as they've continued to accrue allies from across the political spectrum in the effort to expel gender nonsense from policy discussions.
