As much as I want to agree. I can kinda understand where their coming from. I've been on the other end as well, of being judged for anatomy over gender so I know it sucks. But even I have things that turn me off and on of the physical side of things reguardless of the gender of the person. And I don't see how being disrespectful of that is any better than being disrespectful of someone's true gender or sexual orientation.
Personally I may be more mentally flexable with the gender of a person. More about personality for me. But no matter how much I might wish otherwise. When it comes to physical nature, I can not just on a whim, change the fact that some female parts turn me off. I don't like that it is that way, but it is what it is.
I find myself also not sure how to imagine Noah, and I hope whenever/if our characters do get to be with them physically in story, it will be writen in a way that can be flexible to imagination at least.
