Hmm kind of sour grapes mixed with "I turned out fine" and then universalising that to a global proscription

I think that's a big part of it. My father disowned me when I came out as a trans woman and from everything I know about him he didn't have the easiest relationship with gender. He was bullied for being small and weak as a kid because he was a very late bloomer and never really internalized that he was a large man. Like he also fits the diagnostic criteria for narcissistic personality disorder, but I do think his relationship with the punishment for failure to sufficiently perform masculinity played a role. Hell when he tried to convince me not to transition he argued from the position that gender is entirely learned, which is absolutely not the official catholic position he thought it was, but is however consistent with what I'd expect from someone who had the background I described.
