Is Christianity responsible for anti gay bigotry?

[Aegon]

"Least serious"? Leviticus says to kill them. Seems pretty serious to me.

Again Old Testament Judaism Identifies Homosexuality as a Death penalty offense.

Or are you one of those 'smart atheist' who does not understand the bible represents two completely different religions?

Christianity Per Romans 1 identifies Homosexuality as a sin (One among a list of many sins). and Per Romans two tells the christian not to judge/Act against those who sin as we are all guilty of this very same list on one level or another.

"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven." -Matthew 5:17-20

Two different religions, aye, but Jesus says to continue following the old laws. Leviticus is part of the Law, no?
