This is what atheists actually believe.

Last time I checked, all countries where atheism was the state religion were some of the bloodiest regimes in history like the USSR and the CCP.

Russia was despotic before, during, and after the USSR - and consequently before, during, and after an official state policy of atheism. I'm not sure Russia's political trajectory belongs in the religion pile.

China had an encounter with "Christianity" that didn't turn out too well (Taiping Rebellion). Mao's Communist Party was atheist and brutal. But like Russia, China has never known democracy or human rights in its history.

Probably we can conclude government entanglement with religion never ends well, and that includes both theocracies and efforts to forcibly stamp out citizens' diverse religious beliefs - one of the big things our Founders were right about.

There cannot be a civilized society without morals. There is no standard of morality in atheism. All morals that atheist may adhere to are borrowed for Christianity and Judaism. If you eliminate all religions then I give the world maybe 50 years before everyone kills everyone else or a global authoritarian regime takes control and liberty is lost forever.

What you need to look beyond is the Marxism that has infiltrated our society. Marxism is directly opposed to both religion and morality. Marx said exactly that in his "Communist Manifesto". Because of that the American Marxist have lied to everyone about the importance of religious liberty to maintain a free society. Atheists are told that Christians want an authorization theocracy. If that was the case that is what we would have been from the beginning. Instead our founding fathers (all devout Christians) gave us the freest nation to have ever existed.

Opposing religion is in direct opposition to liberty.

"There is no standard of morality in atheism"

Atheism is a position on whether or not a God exists, not a position on morality.

"All morals that atheist may adhere to are borrowed for Christianity and Judaism"

Bullshit. Not everyone's moral system comes from Judaism or Christianity. Do you think morality didn't exist before these two religions (which themselves have many moral problems)?

I think that everybody in the world should have freedom of religion. That doesn't come from Christianity or Judaism.

"If you eliminate all religions then I give the world maybe 50 years before everyone kills everyone else or a global authoritarian regime takes control and liberty is lost forever"

If that were true, then wouldn't every country today that is not very religious be falling apart?

"What you need to look beyond is the Marxism that has infiltrated our society"

Marxism is not atheism, and atheism is not Marxism

"Atheists are told that Christians want an authorization theocracy"

Some do. Not all, but some do.

"If that was the case that is what we would have been from the beginning. Instead our founding fathers (all devout Christians) gave us the freest nation to have ever existed."

The fact that we had slavery for about 90 years clearly means it wasn't the freest nation to have ever existed. Also, not all of the founding fathers were devout Christians.

"Opposing religion is in direct opposition to liberty"

No it's not, because religion and liberty aren't at all synonymous.
