Why is there so much venom and hatred spewed from some of the Christian community towards the LGBTQIA2S+ community?

I have wondered this for a long time. I know some religions teach that gay is a sin. But as I sat in church this morning, I was looking at the 10 Commandments and to break those commandments would be fundamental sins. Yet many politicians are praised and practically worshiped when it is widely known, widely proved that they have broken several commandments.
This isn’t about politicians or republicans vs. democrats. This is a question about why being gay is supposedly so egregious a sin, yet isn’t even listed in the 10 Commandmants. Yet adultery, gluttony, bearing false witness, stealing, etc. are not only over looked, but at times even cheered on.

Please keep your answers respectful as this is in General or I will flag them. Also, this is NOT about politics.
Thank you.
