“Atheism” is the outcome of the ‘old two friends that agree to disagree’, with neither having ‘the winning point’.
“Atheism”, in matters of the divine, defends the non-existence of anything supernatural, and that ‘all’ is a random factor of chance. “It just happens.” Life is what we do, what we think, what we feel, what we become, without any ‘outside determination or intervention’.
Now, “atheism” in politics, a person can believe in splinters of what might form ‘conservative’ or ‘liberal’, but not ascribe to ANY so-called pure party dictate.
“Militant atheism” is, as I understand it, a belief that any and all ‘religious systems’ are an impediment to ‘man’ attaining his highest pinnacle of excellence, due to the chains of dogma and created self-loathing of his self-generated imperfections, and must be removed or destroyed.
In the US, atheists tend to target Christians. They are anti Christian versus anti religion.
Some members of the atheist faith have had bad experiences in their pasts and some have a vendetta.
Militant atheism is the ideology of people too foolish to realize one can’t prove a negative.
