Wouldn't it be a better idea to put the atheists in charge of things ?

Not necessarily... no.
As long as religious people can reason in a secular fashion AND understand that their legeslation isn't there to appease their personal god but has to apply to everyone... I don't have an issue with it. Just respect the seperation between church and state.

Then there is also the idea of atheists being better when they are in charge... I don't think atheism excludes tendencies of bad leadership.

No one's stopping them from rising up the ranks within charities and private services. However, many atheists I know just want to get by on the bare minimum work, sacrifice, and thought, chasing instant mindless gratification.

Like China, I don’t know. ask them,

Like Mao or Stalin? Idk. I think you'd need a better criteria for leadership besides their religious preference

As long as "good" morals are tied up as a hostage with religion, that will never happen.

seems like it worked out pretty well for Germany in the 1930s

and Russa, China, and North Korea these days.

yup sure...why not

Like they where in the Soviet Union which ended in an economic disaster...

It would be good if religion was once and for all put away in the Fantasy genre, as well as the Department of War.
