Religious folks love to say atheism is just another religion. But how far is this conflation of definitions useful? People call all kinds of things religions. Doesn't mean the word religion can apply to everything. Atheism is a religion in much the same way as how not cooking is a way to make food and not playing is a sport. Besides, there is a deeper problem with conflation of definitions. When everything is defined as a religion, what becomes of religion itself? Answer: It gets to hide. Like a crow hiding among ducks after saying all of them are crows.
