Because somehow, disagreeing equals bigoted, intolerant, and insensitive and afraid. Yet, no one simply allows people to disagree. No prejudice involved, there are just some things that people are going to disagree with when it comes to homosexuality.
Oh, and apparently, the above also means that people who disagree with the idea of homosexuality hate all homosexuals. Yeah, no, sorry kids. Assuming things just makes an ass out of yourselves.
Now, if people do kill or assault or do something inexplicably horrible to homosexuals, now that would be the point where many people like me say something along the lines of "that intolerant bastard". Trust me, the disagreers hate the people that hurt people for who they are just as much as everyone else.
Disclaimer: This is simply my opinion. No offense is intended with this stamp. This is simply something that needs to be said since people are so touchy.
