Why does society condemns the relationship between man to man?

Have you ever tried to force a piece of puzzle somewhere it doesnt belong. You cant do it and it looks like crap. That is how society views the bonding of a man to man or woman to woman. They are two pieces that are not supposed to go together. People who try to go against this are going againts the will of society and nature. But who knows they might just win? lots of gay people are accepted my some.

In answer to this question, MysticLingerie claims that society's view on same sex relationships is that "you can't do it and it looks like crap".

I have been in a meaningful, loving, same-sex relationship for over 24 years, and you know what - "we can do it, and it doesn't look like crap" - not to me, my partner, our families, our friends, our colleagues, our town, or the law.
