Just fyi, I'm mildly transphobic, and that guy was still a kook. If I was ever dating a trans person and discovered they were trans, my life wouldn't be ruined and I wouldn't feel lied to.

If I wasn't close enough to them for it to seriously affect me, we'd probably still break up or be at risk of breaking up for quite some time, but hopefully it would be amicable. It would most certainly not ruin my life.

If I was close enough to the trans person that the discovery could ruin my life, it would have the opposite effect. I'd be like "Shit, you're so convincing I couldn't even tell for X months? Maybe I have this all wrong and you're literally the sex you want to be. At this point what's the difference anyway?"

Also just going to point out the part that initially engaged my sympathies. The dude was like "people will be so mad you can't give them babies." But if I ran into a trans person who was infertile, my reaction would be "fuck yeah, no birth control necessary after we both get checked for STDs."

And I'm mildly transphobic. My wife can attest to that, since we got into an argument over Trump's trans military thing. And I'm kind of in the boat where people who take any sort of medication to stay healthy shouldn't be in conditions where you can be deprived of supplies for weeks at a time.
