I don't think it's really that simple. There's an old saying about how history is written by the winners and while there may be some cases where people really should have known better at the time than to support some cause usually everyone sees themselves as the heroes in their own historical narrative and how it is remembered depends on what historical narrative wins out.

Obviously, I support equal civil rights for all people and reject TRA's framing of the issue that they are an oppressed group who only wants the rights that other people have. I feel my support for gender critical activism is consistent with my lifelong support for women's rights and social justice. Of course, I have given this a lot of thought and there was a time when I first started following this issue that I wasn't too sure where I stood on it but I have heard most of the arguments from both sides and that has swayed me (in that I find only one side consistently actually makes logical and sound arguments to be honest) so even if TRA's "win" temporarily and GC is looked at even more negatively than it currently is I will have no regrets for standing by my principles.
