What kind of rhetoric? The fact is that extremists exist in significant numbers when it comes to absolutist forms of trans-ideology. They will brook no discussion, call any criticism "transphobia", publish the home address of people like J.K Rowling and encourage activists to stand outside her house, call "transphobic" any scientific fact that doesn't square with their ideology, want words associated with biological sex to be abolished - e.g. not breast-feeding but "chest-feeding" when midwives talk in certain contexts - lest it offend their ideological beliefs, and push the notion that (for instance) a man who transitions to female, but stays sexually attracted to women, can count as a lesbian.
These things are not rhetoric, they are all things that are are happening.
Maybe you should consider whether what you see as "virtue-signalling" and being "politically correct" may in fact be leading you to falsely believe that are "sides" to be taken. For myself, I'm entirely happy for anyone to self-identify as they wish, provided they don't seek to force their beliefs on me or society in general.
