What gives LGBT groups and advocates the right to promote?

If you find the LGBT opinions offensive or demonizing than that is your prerogative. They aren't asking that everyone gets over their apprehensions about homosexuality, they are merely asking for tolerance and equality from society. Whether or not you approve of someone's sexual orientation does not give you the right to degrade them nor should their sexual orientation have any bearing on the are viewed. And what is dangerous about homosexuality, please don't say the AIDS argument because we all know that its not as though AIDS is running rampant through LGBT communities. If anything it is the intolerance and homophobia that society has developed that is putting the LGBT community in danger. Some people need to pull their heads out of their asses and realize that someone's sexual orientation has almost no effect on their lives.
