Why do religious Christians in America cherry pick sins the most, unlike religious Muslims, etc?

Many religious Muslims are hypocrites too but not to the extent of religious Christians. I am Christian by the way. Just not religious (go to church every week, etc). I noticed the hypocrisy of the religious people of Christianity sects. Muslims try their hardest and not judge as harshly but Christians talk about gay marriage all day, fornicating, yet ignore gluttony. Ironically they ignore it yet when in their religion it says it is a deadly sin. I can care less if you eat a lot, just think cherrypicking is hypocritical.

And same with being gay (I'm straight), if you choose to say this is a sin without other sins? Can't cherry pick, you guys cherry pick too much. Catholic here saying this.
