Are you telling me if you met a hot chick that shared the same interests as you it would be a deal breaker because she has the wrong-shaped genitals or because she has the wrong kind of chromosome? Would you also break it off with a chick that had an ugly vulva?
Your original post did not comment about the
shape of genitals, but about the
type of genitals. This is a very different question, in no small part because you need both working male and female genitals to have children of your own. People sometimes break it off on account that their partner do not want children, or cannot have children. You may find that this is a shame and, fair enough, it is somewhat of a shame. Yet, life isn't all about riding unicorns down a rainbow to find a pot of gold you may spend on beers you'll share with the leprechaun standing nearby. Choosing between someone staying with someone you care about, but loosing out on the chance to father or give birth to children of your own and hoping to get that chance, but only at the cost of breaking off an intimate relationship. That's not an easy choice and both options s*** in their own ways.
Who are you to tell unequivocally to people how they should make such personal trade-offs? You don't get to dismiss their preferences and you sure as hell aren't the person who should be making those choices on their behalf.
I'm attracted to women, not genitals, and if you're only reason to not be with a trans woman is because "they aren't real women and they're icky" that's frankly transphobic.
You apparently do not understand what is transphobia. In fact, you are unwittingly engaged in gaslighting and you're bringing completely undesirable attention to a community of people who just want to be left alone. Stop crying to the wolf everytime someone puts half a toe outside the party line. You're making people increasingly numb to words such as transphobia and there will come a time when, even when there truly is a hateful crime going on, nobody will care because they will all assume it's some intolerant kid engaging in moral posturing again to shut down discussion or trying to bully other people into agreement and compliance.
Do you even know what is transphobia? It's a form of hatred, directed explicitly toward transgender people, it is the intention to take action to undermine their pursuits or to otherwise hurt them. Saying "Sorry, but I am not interested in being a romantic relationship with you." isn't transphobia. Going around insulting transpeople, assaulting transpeople or shaming them -- now, that's transphobic. You don't to pull fake definitions out of your a** to criticize people whose arguments and points of view you apparently do not understand, do not want to understand, continually misrepresents.
You know what I see here? Pure, unadultered moral posturing. I'm calling it out: your concern is fake. You don't give a damn about transpeople. It's all about lording presumptions of greater compassion over the rest of us. Enjoy talking to the wall, alone.
