Same, I’ve never liked pastel hair colours (vivid hair colours were okay) but now I side-eye them all. And I used to be a Goth with black dyed hair and a violet clip-on hairpiece.
Hey not all off us with pastel hair are TRAs some of us are just metal heads !! Plus I’m a Gen z so it’s pretty much common to dye your hair . I will say it’s more common among the TRAs mostly because coloured hair is associated with alt fashion and culture.
I know, I have friends who’d be in their fifties now who are GC (not radfems) and like pastel hair. Like everything else, it’s spoiled the moment TRAs touch it.
I feel you there but it's not like the TRA uniform. The hair is not the problem. It's just hair. Plus I'm such that I see older women in my area who have no idea about transgender politics, getting conned by some gen z tra nazi into a trans (blue pink) dye job.
Also when I was a teen I loved coloring my hair different colors. Now I associate colored hair with genderists ☹️
