I miss the era where a woman could be masculine and a man feminine without being considered trans. "Gender is a social construct" and all that, remember? That was less than a decade ago. I will never understand why the left became even more rigid on gender roles than the right, but in a different way.
They still can be.
Based on everything I read online, that's pretty much not the case in leftist circles anymore. There are way too many stories about teens or even people younger deciding to socially transition today.
