I wasn't really "raised to believe" anything. I don't know if it's cause I'm Canadian, or what. but my parents never even touched on this topic when I was young. They never had anything to say about gay people, races, abortions, or anything else controversial. The closest thing I got to something like that was when I was going to Barbados in 3rd grade, I was told that there were a lot of black people in the caribbean, and to not act differently around them.
and honestly I'm glad that's how I was brought up, as a blank slate. now I form my own opinions.
Personally I don't give a fuck whether or not gays get married. if they want to be with one person with the rest of their lives, then so be it, who fucking cares? they will either be miserable and get divorced, or happy until they die, or be miserable until they die. how is that different from straight people? pro tip: it's not.
to me, marriage is simply a bond put on paper. straight people don't have to love each other to get married, but when gay people are in love they can't get married? that is fucking gay. I'm not necessarily for gay marriage, but I don't even care, do what you want. One of Confucius' 5 reasons of conflict is ignorance of history/fact. I think that anyone who is opposed to gay marriage falls into the category of ignoring fact. Marriage will be the exact same if same sex couples are permitted to be married, so build a fucking bridge and get over it.
