It completely escapes me how Robertson, and many like him, are completely unable to see how their words and actions lead to anti-gay bullying. If religious fundamentalist leaders, spokespeople, parents, and teachers consistently tell children that gay people are evil, sinful, disgusting pedophiles, then why are they surprised when those same children act out on that messaging and attack people they perceive as being gay?
So many young people are constantly worried about what others are thinking of them. I think anti-gay bullying, in a way, is a self-protection mechanism that young people can use to keep others from thinking they are gay, and therefore making them the victims of the same bullying. It's all a vicious cycle of fear and control. Can you think of a system of belief that is largely based upon fear and control? I can think of a few.
It's possible that Robertson and his ilk think they are acting from a place of love and helping to bring people closer to God. Personally, I think they can shove their specific brand of Christian love straight up their asses because I have no use for it. (I realize not all Christians believe as Robertson does, but far too many do.)
Yes, Robertson is right in that anti-gay bullying is wrong. But it's not wrong for the reasons he thinks.
