I, personally, am not homosexual, bisexual, or even sexual at the moment (Waiting until after high school). But I absolutely HATE it when one of my friends who IS homosexual or bisexual is bullied simply because of their interests.
In my opinion, the people that bully them are stepping WAY out of their place. Honestly, who are they to say that my friends can't like someone of the same gender? Who are they to tell my friends that they can't be in love with who they're in love with because some dusty old book says that it's wrong?
You know what I think is wrong? People thinking that love is something that can only happen between two people of the opposite sex.
