Theory of Evolution, Atheism, and Homophobia.

[Aoi Magi]

As I said before, I don't have that much of a good knowledge regarding the theory of Evolution. However, I did learn some of the headlines you might say during Introduction to Psychology class. The professor said that according to the theory, our primary purpose is to reproduce, they went (gender neutral pronoun) as far as to claim that nature tricks us into thinking we're in love, but the primary purpose is just to reproduce.
 
From that point of view, and as a gay man myself, could the theory of Evolution based on that interpretation be used to justify homophobia? After all, this is basically what the Roman Catholic Church says about marriage and sex.
 
What do you think? And while we're on the subject of homophobia, do you think homophobia would still exist even religion didn't? What about China, Soviet Russia, and also Estonia which is predominantly irreligious but LGBTQ people have had tough times.

evolution and natural selection has no "purpose", neither do we as individuals except for what we make for ourselves. We can choose to be immortal cyborgs and evolution would still continue despite the lack of natural reproduction.

Humans are afraid of anything they don't understand, and homophobia is rooted in this fear.
