From what I experience personally in real life and online spaces, I would say that the majority of TRAs are women and the majority of people fighting against trans ideology are women. Bearing in mind that I'm a Mumsnet user in Ireland. Of the TRAs that I know personally they are more likely to be young Gen X men and Millenial women. Older Gen X men and pretty much all Gen X women that I know are either Terfy or don't really care but still terfy if pushed on issues like sports, prisons and puberty blockers. Of the Zoomers that I know, the men/boys are more likely to be quietly terfy and the women/girls are mostly still tras.

And when it comes to the Gen Alphas I know, who are old enough to have an opinion, they think the idea that you can change sex is stupid. Some of the Gen Alphas are borderline homophobic. (Also, bit of a tangent..... but, they laugh at the idea that cow farts can destroy the planet). Overall, they are questioning the 'truths' that the generation above them has had pushed on them and finding them suspect.
