Oh OK this can turn into a proper discussion!
Agreed Diva, and I can't say I am a fan of trans people being being reduced to token fantasy objects. Nevertheless, they shouldn't have their sexuality entirely removed for the sake of political correctness: there has to be a respectful dividing line. On Lit cis-men and women are objectified; language is open and often coarse... just as it can be in a bedroom.
I think it's actually ok for CDs, subs, "bois" to be able to have freedom to ... do whatever it is gets them off through Lit. I don't have images turned on by default, but if I browse through a thread and see people using language that is abusive or just plain scarey, then I'll pitch in and say something and I think the Mods do the same.
If there was some automatic insert that popped up every ten posts that said "You do realise this is fantasy, right?" then people would soon tire of it. I think we have to trust the majority of active posters and commentators to understand the context. People will have the fantasies no matter what and that includes trans people.
I can see from your post you weren't meaning to stop people either. I hear you and I think I'm in agreement too
