I voted YABU because I disagree that that it is automatically about intimidation and control. A transwoman who genuinely believes they are a woman cannot be doing it to intimidate and control other women because they genuinely believe they are the same as those women, and therefore them getting undressed in front of them is no different (in their eyes) to another woman getting undressed.
Yes I believe that some (probably most) men pretend to be trans in order to intimidate and control. But not all cases. It depends on the individual and their beliefs.
You and I may believe that a person cannot change sex or gender, a man cannot become a woman, it's bloody obvious, but just as we firmly hold that belief there are others who are certain the opposite is true. A "genuine" transwoman believes they are the same as a real woman. This shouldn't be a surprise, the last couple of decades has convinced them this is the case. (I know the groundwork was laid in the 70s when their was a proliferation in rights for marginalised groups, but it's more recent that it's become mainstream.)
Honestly, for a while I believed it was possible. I was groomed through an 80s and 90s childhood that we had to accept others for who they wanted to be.
