Wow, so much to unpack…
In fact there are atheist churches. Many churchgoers who now identify as atheist missed the congregations and the assemblies, so, they started atheist churches. I don’t belong to one and I would not treat my atheism like a religion. Still, atheist churches do exist. Search ‘Morning Assembly.’
Do you have a citation for this? I believe what the supreme court said is "Atheism is protected under the First Amendment just as religion is protected.’ In short: you have a first amendment right to free speech about your religion. That allows you to knock on doors and scream from street corners. Atheists have those same rights under the law.
Preaching is not a submission of ideas, it is a regurgitation of dogma, especially when it comes from the bible. These ideas are the best thinking of Iron Age goat herders and the people that once ruled over them. That does not imply that there are not some useful ideas in the Bible, but as evidence for the existence of a god, it is a collection of superstition, mythology, Iron Age logic, and very much useless.
Argumentum adpopulum: The popularity of an idea does not make it true. People once believed the world was flat. Mythrus was popular before Jesus, as were the Roman and Greek Gods. Popularity does not breed truth.
A better question is why aren’t they offensive to you?
1 Timothy 2:12 Subjugation of women: 1 Timothy 2:12 But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence.
Matthew 5:30, And if thy right hand offends thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
The entire concept of Hell is offensive. “Love me or burn in hell?” Really? Now that is one fucked up message. Your god sounds like a stalker.
But remember, once you cut your hand off, you can not go to Church ever again. "For whatsoever man he be that hath a blemish, he shall not approach: … Leviticus 21-18
"But if this thing be true, and the tokens of virginity be not found for the damsel: Then they shall bring out the damsel to the door of her father’s house, and the men of her city shall stone her with stones that she die…’ Deuteronomy 22:20
If your brother dies, you need to fuck his wife??? Really? “Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.” (Mark 12:19)
God loves everyone unconditionally… well … unless they are deformed by cutting their hands or balls off. “He that is wounded in the stones, or hath his privy member cut off, shall not enter into the congregation of the Lord.”(Deuteronomy 23:1) Oh! And unless they are a bastard. “A bitched shall not enter into the congregation of the Lord; even to his tenth generation shall he not enter into the congregation of the Lord.” (Deuteronomy 23:2)
“For every one that curseth his father or his mother shall be surely put to death: he hath cursed his father or his mother; his blood shall be upon him.” (Leviticus 20:9)
Your Family Is Your Enemy and You Are All Competing for God’s Love? What a sick book. “For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man’s foes shall be they of his own household. He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.” (Matthew 10:35-27)
“I permit no woman to teach or have authority over men; she is to keep silent.” Timothy 2:11
“Happy shall he be, that taketh and dasheth thy little ones against the stones.” (Psalm 137:9)
Divorce And Remarrying Are Both Considered Adultery. “Whosoever putteth away his wife, and marrieth another, committeth adultery: and whosoever marrieth her that is put away from her husband committeth adultery.” (Luke 16:18)
Both Malachi 3:6 and Hebrews 13:8 declare that God is the same always and never ever changes. If you are trinarian, your Jesus is the same god that sanctions slavery, murder, rape, and the killing of babies. How do you not have a problem with this?
