Atheist infighting, political polarization and the decline of global atheism

Is atheist infighting going to contribute to a decline of global atheism in the 21st century?

In 2017, the atheist activist Lee Moore indicated about American atheist organizations:

If you look at the major atheist groups right now, like the national groups, the ones that are doing the real activist work... They are not bringing in the kind of donations they used to. Most of them are starved for cash. They're downsizing left and right. Because people aren't just giving like they used to. And I talked to a lot of the major donors out there and they said, "Well, we're kind of tired of seeing the atheist community just fight amongst itself and not really get anything done. We'd rather not give money if we don't think it's going to go somewhere.

Atheist Dr. Gordon Stein wrote:

Atheism has long ceased to be a rare and oft-ignored philosophical outlook...It has transformed itself into an active political programme with clear objectives which, though they vary from state to state, unequivocally include the elimination of state religion, religious education, and the enshrinement of scientism (Gordon Stein, Encyclopedia of Politics and Religion, page 74.). 

There is a reactionary element to atheism, For example, the atheist ideology in Muslim countries is a reaction in part to Islam.  On the other hand, the atheists in a culture absorb various aspects of that culture.

In the  Western World,  right-wing, populist nationalism rising in Europe and the United States has increased the prevalence of the secular right within Western atheism. In addition, there is a backlash against feminism within atheism - especially after the Elevatorgate controversy which involved feminists disparaging Richard Dawkins. 

Historically, the atheist population has titled on the left side of the political spectrum.  For example, according to the University of Cambridge, historically, the "most notable spread of atheism was achieved through the success of the 1917 Russian Revolution, which brought the Marxist-Leninists to power." According to the Pew Forum, in the United States: "About two-thirds of atheists (69%) identify as Democrats (or lean in that direction), and a majority (56%) call themselves political liberals(compared with just one-in-ten who say they are conservatives)"

So what is the net affect of right-wing atheism rising within American atheism?

In June 2016, American Interest reported:

First of all, religious belief is still very powerful and widespread, and there is nothing inevitable about its decline. In fact, the proportion of people who say they believe in God actually ticked modestly upward, from 86 percent to 89 percent, since Gallup last asked the question in 2014.

We do live in a multivariable world so atheist infighting might be one of several variables that is causing the promulgation of atheism to be more challenging in the United States.

China and Europe are the two geographic regions where are atheists are the most prevalent. As alluded to above, in Europe right-wing nationalism is rising in reaction to Muslim immigration and anti-European Union sentiments. This is going to cause right-wing atheism to rise within European atheism. And since European atheism affects American atheism, it should cause right-wing atheism to rise within American atheism.

Now when you consider that China is experiencing an explosive growth of Christianity and atheists infighting within Western atheism will in all likelihood increase, the future of atheism looks very bleak.

In 2012, the W. Edwards Deming Institute published a report by the World Future Society which stated:

In 2100, however, the world will likely be only 9% unaffiliated — more religious than in 2012. The peak of the unaffiliated was in 1970 at around 20%, largely due to the influence of European communism. Since communism’s collapse, religion has been experiencing resurgence that will likely continue beyond 2100. All the world’s religions are poised to have enormous numeric growth (with the exceptions of tribal religions and Chinese folk religion), as well as geographic spread with the continuation of migration trends. Adherents of the world’s religions—perhaps particularly Muslims, Hindus, and Buddhists—will continue to settle in the formerly Christian and ever-expanding cities of Europe and North America, causing increases of religious pluralism in these areas. Christians and Muslims together will encompass two-thirds of the global population—more than 7 billion individuals. In 2100, the majority of the world’s 11.6 billion residents will be adherents of religious traditions.
