Atheism & Rationalism are in a broad sense, the rejection of belief in the existence of deities or any view appealing to reason as a source of knowledge or justification. In recent times people who ever says they’re atheist and rationalist, they doesn’t seems to be having reasoning knowledge or justification. They say it because their personal life deficient, inability to adapt to society, disabled thoughts, and some cracks says “I am atheist/rationalist” for fashion, etc. Sorry fake atheist & rationalist, this is the truth about you. I still believe in atheism and rationalism, it makes lot of sense.
