You're wrong. They believe in and love Godde and are a lot more Christian than you. Jesus never railed against LGBTAs and abortion, he treated women as equals, he healed the sick at no cost, he stressed peace, non-violence, love, equality and charity and called out the wealthy and powerful.
The Bible was awkwardly translated from ancient forms of Hebrew & Greek. People back then had no concept of "sexual orientation". The alleged lines against homosexuality were really anti-Pederasty (when a grown man molests an adolescent boy as some sort of freaky 'mentoring/romantic' type thing) or temple prostitution (which often involved sexual slavery and the molesting of kids).
Jesus was not a prudish legalist. He cared about stuff that counted, like being kind to each other and helping the less fortunate....and even HE was willing to bend and break the Mosaic Law.
When Jesus said He came not to abolish the Law, He was not talking about the Law of Moses....that is more a "National Constitution" for the Ancient Hebrews. The Law of Godde would be the Noahide Laws and The Original Decalogue....Which are Seven or Ten laws (The Decalogue is more for the Jews whereas the Noahide is for Non-Jews). They're similar and Universal: Don't Murder, Cheat, Steal, etc. (common sense stuff).
Jesus Condensed it all into just this....Love the Supreme Power behind All-That-Is and simply "Be Excellent To Each Other"....everything else is just commentary (as another famous Jew of yore once said).
These things should just be guidelines, scary tyrant Godde is a human distortion and "Godde" in these Laws can be defined as any "Higher Ideal" or "Providence" IMHO. To me; Godde is Deity and is followed in all faiths.
Now ditch the authoritarian need for control and embrace Reason. You can still embrace Reason as a person of Faith. Deity gave you a brain and the ability to reason, USE IT!
