Well, you’re moving the goal post here. First you said homosexual relationships would result in the end of the species. That’s not true, and I just showed it.
Being homosexual doesn’t mean we don’t involve men at least. It’s not about rejecting men. No one wants to do away with one gender or their other l. Of course I understand men and women need to work together to have off spring. I don’t deny that and never will. Being homosexual does not mean rejecting one sex or gender. I happen to like men! I have lots of male friends, colleges, and I’m not here to decimate them from the earth, nor does being homosexual mean that. Of course both men and women are needed for reporodiction, but that doesn’t mean not dating each other will lead to the end of the human population. Saying I don’t want to date men, and can still have kids doesn’t mean the same thing as men don’t matter. It’s kind of the old homophobic argument that some how lesbians hate men and are lesbians because we just hate men, which is false. My Dad, is my favorite human ever is a man, and so are many friends and colleagues. However, dating men is not necessary for the human race to continue. Yes, having them give up their sperm is, but for me as a woman, sex is not involved, nor is dating, and that’s fine.
You said if people stopped dating the opposite sex human life would end, this statement is false, just own it instead of changing your argument to something else. I never said we don’t need men, just heterosexual relationships aren’t necessary to keep the human race going. There will always be people who date the opposite sex, that’s fine, but we can still procreate without them.
