it's such an interesting logical jump to hear "I'm a homosexual, and therefore not interested in dating or sleeping with any members of the opposite sex, on account of their sex" and transform it into "I am reducing an entire person, with likes, dislikes, hobbies, feelings, beliefs, and values into a set of genitals"
excluding someone from your dating pool for any particular reason does not mean reducing their entire personhood to that one quality. if I didn't want to date a person in a wheelchair because I'm fond of outdoor hiking, trail bike riding, and swimming, it does not mean I am reducing a person in a wheelchair to their wheelchair, I can still recognize their personhood and their humanity, while also recognizing a quality that would make us incompatible partners. If I was a pious Christian and unopen to dating someone Buddhist, it does not mean that I am reducing their entire life, personality, or humanity to their religion, I am simply recognizing a quality that would make us incompatible. Saying "this particular characteristic or quality makes us incompatible for dating or sex" is not the same as saying "I do not see you as a full human being because you possess this characteristic or quality." to take it farther, I am also not interested in dating or sleeping with any of my family members. this doesn't mean I am reducing every single family member to their familial tie with me, I recognize that they are full human beings with full lives, but the fact that we are related is kind of a major thing that makes me uninterested in thinking of them in that way, that quality, the familial tie, makes me exclude them from the romantic part of my life, and keep them strictly in the family part of my life. I could go on and on with examples. I also would not date someone who only spoke Spanish, and didn't speak any English, because we would not be able to communicate. does that mean I'm reducing people to their native language? I don't think so. I wouldn't date someone who I'm physically incapable of feeling sexually or romantically attracted to on account of their sex, does that mean I'm reducing someone down to their sex? no. male people can be fully realized human beings with personalities and beliefs and experiences. but I still am not attracted to them, not because I see them as just walking penises rather than people, but because I was born homosexual. I see them as a full person, just not a type of person I'm attracted to. I'm also not attracted to elderly people, obese people, and lots of other kinds of people, but I still treat them with basic respect and see their humanity despite my lack of attraction to them. that argument is so fucking stupid and crumbles with even the slightest criticism. it's just another way to claim that homosexuals are shallow sex-obsessed genital freaks who aren't willing to see the humanity in the opposite sex. no, I see your humanity, and I still don't wanna fuck you!
