Why are people such bigots?

Why are religious people such bigots and why do they judge when if there is a God he said judge ye not lest ye be judged? Religious people are against gays and yet God, if he exists, which is highly unlikely, said we should not judge. And surely gay people are the creation of God too, if he exists, which is highly unlikely. The scriptures were written some 300 years after Christ and each one has plagiarized the other. It's rather like in 300 years a few writers record what Blair has done, and exaggerates and adds their own ideas which eventually would become the 'truth' as in the scriptures. There is no God, he is an invention of King Akenatum of Egypt who decreed that his people should stop worshiping the moon and the sun as they weren't responding to requests, so therefore there must be an invisible God....yeah right love....so all the people then worshiped this supposedly invisible God. Moses took the idea to Israel and hey presto, religion is born and has caused trouble ever since. There is no God, get used to it
