From a scientific perspective, what's the reason for, and advantages of being gay?
Like from my base understanding of biology, life exists to breed more life. Being gay is, literally, driving a creature toward the opposite of that.
How come this trait hadn't been snuffed out by evolution?

/pol/tards and leftcucks please fuck off, I am looking for biological / scientific input on the topic, I really don't care for <current year> political brain rot, I just want the science that answers my questions.
