I've learned that homosexual and heterosexual marriages, relationships, and people are alike in many ways with their exceptions. Hetero and homosexuals argue over the same things, and have many of the same preferences

Question:
So why is it that homosexuals are seen as outkast and heterosexuals are the almighty?

Choices:
Culturally incorrect
Against Religion
Unexceptance passed on by family

 

Because if people want to hate them, they will, and people, they love to hate them. (In your title, you say "proven" study, maybe a vague reference to the study would be nice?)
