There is a difference between tolerating and joking about something.
To me, tolerating gays is like...knowing in my heart and mind, that I hate the act (not the person) of homosexuality.
This implies that I may not dislike the person themselves, but their actions.
And I will not say to their face the things i think are wrong with what they do. I...I myself do not say mean things TO them. I could think them and have every right to my thoughts, they are what guide me. I will not go up and like, physically hurt someone, or meanly say something offensive to a gay persons face. This to me, is tolerance.
In comments, I am not personally offending anyone. If they are offended..it is by what they take from it. You either brush it off, or take it personally. Which might be leading to a guilt?
