Quark Atheism, also Quarkist Atheism, is an atheist ideology and movement that seeks to embrace the atheist ideas and politics of Quarkism. Quark atheism is characterized by the full countering on spirituality, religion and immaterial beliefs together with the full replacement to them by materialism and atheism through materialist education, and that since the kindergarten that should have materialist education and that mass media and internet should be used in order to provide materialist education to everyone else. Quark Atheism also support that atheists should unite themselves in order to turn all countries into state atheists and make bills and laws to outlaw and make religion, spirituality and immaterial beliefs illegal and send spiritual people, religious people and people with immaterial beliefs to psychiatric hospitals to be "cured" or even for life in case the one don't want to give up their beliefs. Quark Atheism also supports that scientism, anti-theism, atheism, secular fundamentalism, materialism and physicalism should be taken into their last consequences and that only quark atheists and atheist fundamentalists are the true atheists and anyone else are moderates, such as new atheists, or religious/spiritual people in disguise, such as spiritual physicalists and spiritual atheists.
"Quark Atheism is just extremely radical and shows that atheism can be really radical and extremely secular fundamentalist sometimes. But still, while quarkism is not hegemonic, there's nothing so much to worry about quark atheism."
