Disagreeing with another's decisions in no way, shape, or form insinuates bigotry. I can disagree with tons of beliefs, but it doesn't mean I should or would treat them any differently than my best friend or family member. Why is that so difficult for some to comprehend.
So far, the biggest example of bigotry is coming from those in favor of homosexuality. How can you not see the irony in this? I believe that above all else is love, and even though I don't agree with you, I should still try to love you with all of my heart and hope for the best for you. It is easy to lump religious believers into an intolerant, unintelligent, non-progressive box. Yet many also lump homosexuals into a nice, neat box also. How is that any different than what you're actively condemning?
Say I'm a gay 16 year old kid. If I'm being raised by a "love the sinner, hate the sin" parent, I'm being told that I'm not good enough. Then I have to go to church with said parent and hear comments, sermons, etc. about how there is something wrong with me because I'm gay. I go to school, and kids make fun of me because I'm gay (after hearing their parents and church talk about how it is a sin). I read message board threads that talk about how my sexuality is the equivalent to lying, cheating, and stealing. People make comparisons between premarital sex and homosexuality, without acknowledging the fact that I likely can't get married, but the abstinent couple will be able to go at it like rabbits once they sign that piece of paper. Oh, and since these people all believe that God makes everyone, it is clear that either God hated me when I was still in the womb or that I'm choosing the most brutal "lifestyle" imaginable.
That gay kid doesn't affect your life because he is gay. People standing up for gay rights don't affect your life. You "disagreeing" with the homosexuality? THAT actually affects people who are often struggling from all of the BS thrown their way simply for being themselves.
