The adherence to anti-religious ideology that militantly ridicules, mocks, scorns and satirizes the idea of the existence of a deity or deities and or religion, indifferent of feelings of bigotry intolerance hatred and persecution that adherents feel as a result. That does not respect religion or support policies supporting the freedom of it. Calls for its abolition or severe restriction & for religion to removed from public life. Puts forth fact-based arguments, propaganda & bullying and insults as tactics to push adherents to abandon their professed beliefs and or convert them into like-minded individuals. They regard religion as inherently harmful. Secular-Fundamentalists aren't themselves religious by definition however their attitudes regarding their beliefs mimic many religious fundamentalists so much so that the manner of their expression of their beliefs is often indistinguishable in form, from their religious fundamentalist counterparts. They commonly use a myriad of semantical arguments to avoid being labelled and most often use the internet to spread their message. They ignore rational counter-arguments regardless if it is supernatural or science based. They may exhibit obsessive-compulsive behavior regarding religion and related issues often taking disproportionate offence to even subtle outward expressions of religious belief and feeling compelled to constant dispell religious ideas. One may or may not subscribe to a deity to follow this ideology.

A militant atheist is one who is hostile towards religion. They differ from moderate atheists because they have the desire to propagate atheism and also hold religion to be harmful. Militant atheism was an integral part of the French Revolution, Soviet Union, Cultural Revolution, and is expresses itself today in the ideas of the New Atheist authors.
