Ok appreciate it does sound homophobic but science and nature intended for male and female in order to breed and reproduce and this is a default teaching to any child... guessing I am wrong again with this... please don't hate me!“
Science and nature have no intent.
Science attempts to understand, describe, then predict what nature does. (There are good genetic explanations for homosexuality. Homosexual behaviours occur in animals as well as people, for example).
Human reproduction follows from penetrative sex between a male and a female person, very occasionally. That's a description of nature. Not every instance of sex though. Not every person, or every couple. Not every hetero person or hetero couple.
So if, according to your worldview, the point of all relationships is children, then what is the point of love, or marriage, companionship, or most sex, given that none of these reliably results in children? What is the purpose of hetero people who don't have children? How do you explain or excuse them? Surely they are as problematic for you as homosexuality?
Then, what is so great about reproduction, about more children? Aren't there enough already? Why would overpopulating the world be viewed as a good thing, per se?
So whose intent and whose teaching are you talking about, exactly?
