1. fail to see your point in bringing up chinese culture into this debate bc there have only been he/hims and she/hers for 2000 years
2. bi is the same as pan, asexual still makes you gay straight or bi, you're either interested in sex or not at all, and the same goes for liking someone for their personality
3. no, because genders and sexes are the same thing. your sex/gender is either male or female, none of this non-binary or trans bullshit
