See, this is the problem To you, it's only "tolerance" if I agree with 21st century values. What you fail to realize is that is by having that belief, you are being intolerant. Gay marriage is a sin in my religion, but if I say that, I am ridiculed. Being gay is not normal. The human body was not designed that way. Men and women fit together for a reason.
A perfect example of the intolerance that we see in America is with the left and Cathy family. Truett Cathy is the founder of chic-fil-A. He did more humanitarian work than any other billionaire, the Gates included, but because he was a Christian and believed the bible he was protested and ridiculed.
More examples of American hypocrisy is the DNC convention. You say that we should support homosexuality. This is one of your parties core beliefs, but then you fly a Palestinian flag at your convention.
