I think modern X-Men is reaching a tipping point in terms of their featured characters and sexuality. It's just not realistic for every book to be completely "inclusive". It's not an issue of representation but improbability. And that's not just in terms of sexuality but race, creed etc. Everything doesn't have to be the United Nations of "Like me". I survived for years with Storm and Bishop being the only "black" characters in the entirety of X-Men (Bishop is Aborigines). It doesn't kill you.
Same thing goes for these morlock types that every X-Men artist seems to populate the background with. At some point someone has to realize that there's no chance that all these people are compatible enough to reproduce. Eventually you end up with a bunch of Rogue-like situations where Frog-Boy and Mist Woman aren't biologically or logically able to romantically interact, much less reproduce.
Seriously, in the past 20 years how many characters have "come out of the closet" or just been insinuated to be one thing or another? I mean main characters. Psylocke, Iceman, Shatterstar, Rictor, Rachel, Kitty, Rogue, and the latest Cyclops and Wolverine. Probably missing something. It's just getting a bit much. That's like half the main cast. And let's be truthful, in the pantheon of X-Men, there are only 12 that really matter, despite what editors and writers try to force down our collective throats.
