Odd part to me about this is those preaching tolerance are very effectively using this strategy to unify all beliefs into their own by making it a moral / social crime to believe anything but what they believe.  Originally "tolerance" was the idea of allowing everyone to co-exist without persecution.

Marriage should be between man and woman = hating gays = killing gays = nazi germany.  It's all equated to each other.

I have no problem with gays getting married.  I do have a problem with the faulty pigeonholing / aggregating thought sins as equal to action sins.
