Personally, for me it’s the idea that just because you don’t experience something (dysphoria, or being a gender other than what society expects of you) that doesn’t mean those experiences aren’t valid.
I get sooo tired of the response “I just don’t understand! I love being my AGAB! Why can’t you just get over it?”
That is a good point. Almost as if being cis is taken for granted. Like its an automatic state of self. “Of course I’m my AGAB” but they never experience the relief and happiness that comes from finally being your true self.
