Summary
This quote suggests that atheism should not be classified as a religion, as it is essentially the absence of belief in a supreme being. Comparing atheism to calling baldness a hair color implies that atheism is not an affirmative belief or belief system, but rather a lack or absence of belief in deities. Just as baldness is the absence of hair, atheism is the absence of belief in a higher power, and therefore should not be equated with religions that advocate specific beliefs and practices.
