I respect them, but I don't fully understand them. Xenogenders are kinda just a ~vibe~ and I'm not here to kill someone's mood. Although I agree with Randumb, I will ask if I can use they/them, and if I can't, I will just call them by name exclusively lol.
((However, I feel like Xenogenders can sometimes can give LGBTQ a bad rep and make us seem silly. bc you KNOW some queerphobe is going to say "OmG!!1!! CaTgEnDer?? thAtS sO sTuPiD LgbTQ iS fULL oF dUmB cHiLLdRen!!!1!11!"))
