I don’t wanna fuck any women.
And the lies begin. What would be the relevance of you saying:
As a straight dude, I’m not about to call another dude ‘miss’.
If this has nothing to do with sex?
Also why should I treat any category of person with respect just because of their category?
You should treat every person with a basic level respect just because they are a person. Once they reveal themselves to be a misogynistic piece of shit you can stop doing so, but even then I'm not going to misgender you just because you're an asshole.
And how do you determine if it's true?
Someone created a Cis or Trans Quiz with 25 pictures: https://uquiz.com/quiz/ACfqeR

It takes less than 5 minutes, feel free to link your perfect score (Note how only 78 people scored higher than 90%). Otherwise your only options to determine if it's "true" would be insisting on seeing their genitals, making you a sex offender, or to take them at their word.
