Does God not allow gays and people of other religions into Heaven?

I am a believer in God but, something I cannot believe in is that he would not allow good people; be they gay, non believers or of other religions into heaven. If God is a loving God then why would he not love all his children. This completely baffles me because people have it all wrong. Why hate your neighbor because he is different? Why persecute him/her because their lifestyles don't match your own and who are you to pass judgement? A bunch of hypocrites and ignorant SOB's are spreading the word of hate among the world. What do you think?
