When exactly did trannies become normalized?

what if the transphobes are right

like what if I'm really just a delusional mentally ill autogynephilic man who takes pills to grow tits and changed his name and grew out his hair and likes wearing dresses and skirts and cute bracelets but will never really know what it's like to be a woman and should be using the men's restroom

sometimes the amount of transphobia in the world makes me wonder how I got literally everyone I know to call me "her" the same way they would if I were a cis woman. even random coworkers who I barely interact with will respect that I identify as a woman. it feels like a really lucky coincidence that I've never had to deal with transphobia irl, especially since I live in Texas. but I don't know if I should feel grateful or guilty.
