Hard to tell, but considering this video is what caused my egg cracking, the video hit the nose on all the excuses I was using.
The main reason I thought I wasn’t trans before my egg-cracking is that I didn’t know what dysphoria looked like, and I didn’t think I experienced adequately severe dysphoria or that whatever gender in-congruence I felt was “clinically relevant” enough to count as trans.
I would read the DSM-V criteria and think “that doesn’t match my experiences”.
What helped change this (besides those Transition Channel youtube videos) was reading The Gender Dysphoria Bible, reading Julia Serano (esp. Whipping Girl and Sexed Up), reading Mia Violet’s Yes, You are Trans Enough, and reading peer reviewed journal articles, like Dick Swaab’s work (e.g. this 2008 article).
