Reality demands same sex partners CHEAT on their partner to conceive future generations!
Did you just go around to a bunch of different cities and copy and paste the same argument to make it look like more people agreed with you? I've seen you write this same comment like five times. That doesn't change the fact that it's a faulty argument. But just so other people can see, I'll paste my previous answer too how does that sound.
Are we at a place where we're facing dire under-population and concern that the next generation won't exist, or something? Or has the world population gone over 7 billion people? Furthermore, plenty of heterosexual couples are unable to produce children without in vitro fertilization (maybe the man's sperm can't fertilize the egg, or the woman experiences anovulation) or surrogate mothers (woman had a historectomy, etc). Are these couples cheating in these cases? I don't think so.
Same-sex couples that resort to the same measures are not cheating on their partners either. Also this argument implies that the only reason for marriage is to produce offspring, when there are plenty of happily-married couples who do not have any children. Are they unfit to be married as well?
