I'm trying to have them all more mature so Karkat doesn't want to pretend he hates either of them XD he really doesn't anymore and there's no hiding it. It's not like they're all in a hurry to fill all of their quadrants either, they're still pretty young! and considering how incestuous that'd make the group, it means quite a few of them will probably fill some out-group anyway.

Yeah, a lot of humans are weirded out by trolls, since unlike the kids they didn't learn to see them as male/female first and then learned they had both in their pants, even if mentally they usually matched their appearance. It's yet another "trolls are freaky" thing. Then again the trolls think of humans as genitally mutilated and stuff. It's freaky on both sides.
