Just look at the eastern bloc after the fall of the USSR. Religion returns.

It was never gone, just went underground where forbidden outright and it even flourished because it became a uniting element against the state.

Not always (cf Czechia and East Germany).

That doesn't mean China has no dogma, it means atheism is its dogma.

Google's definition:

dogma: (noun) a principle or set of principles laid down by an authority as incontrovertibly true

Atheism is not dogma. That's wordsmithing to help believers in god feel comfort in a false equivalency between conception withour sperm and the cosmos / observable world empiricism.

I didn't say atheism itself is a dogma. Rather, the Chinese government (an authoritative body) has dogmatized the atheist worldview by requiring that it be held as incontrovertibly true.

This isn't "wordsmithing", it's a dictionary-perfect example of what dogma is. I think a lot of folks recoil at the idea of atheist dogma because of the history of Christianity-as-law in Europe, especially medieval Europe. But this shouldn't be taken to mean that positive religious beliefs are the only possible beliefs that can be held as dogma.

Atheism is not dogma when you choose freely your belief in the not existence in God.

In China there is not freedom, and you are forced to believe on it whenever you want it or not. This is dogma.

Not all believers in God believe in Concepcion without sperm. This only applies to puritan Christians that believe in literal interpretation of the Bible. Not all believers in God believe in the Bible, not all that believe in the Bible believe in its literal interpretation, in fact hundreds of millions of people do not.

And science tells us that is completely possible to have conception without sperm. There are animals that could reproduce either asexually or sexually and in the next 20-30 years it will be routine for us. We have already mixed the DNA of three parents.

Most of the people that made great contributions to empiricism knowledge of the world were in fact Christians. This is a false dilemma.

Atheism certainly can be dogma, especially in the strong variety. It is usually also coupled with a healthy dose of scientism.

Yea, science is often weaponized by non-scientific people as an im-smarter-cudgel.

Atheism is not dogma, correct. But communist systems tend to employ an evangelical version of atheism that seeks to supplant traditional religions. So perhaps the more accurate word should be "anti-theism", not atheism, which is a much more generic term.

It's more of a cynicism towards institutional beliefs. It wasn't handed down by anything. Most likely due to the events of the Cultural Revolution and Great Leap Forward where old institution were destroyed by the existing shitty institution leavig people with dirt and craziness. The new God that emerged from the rubble was Money.

Of two dogmas that are opposite to each other one must be closer to the truth. Guess which one it is.

Please don't do generic religion arguments here. It's unsubstantive and converges to flamewar.
