Truth is Truth
For 26 years I have refused to believe in a divine being of any sort, and I am glad that there are others who agree with me. Although I severed my connection to the alleged-godhead at the age of 12 in a fit of pique, I have used logic, history and rational analysis to continually come to the same conclusions and maintain my vigil against the God-fearing among us.
Upon admitting that I am an atheist, I experience a range of responses; anything from the old and trite utterance, "There are no atheists in foxholes," to the intentionally patronizing "That's okay, Jesus loves you anyway." Undoubtedly at some point, all of you will experience things like this, but I caution you to not become angry.
Religious belief is just another kind of ignorance, like anti-Semitism or racism or misogyny. Any attempt to broker understanding to another human being purely through words will only end in failure. You must live your life in what they might term a moral fashion, and show them through deeds that even the 'godless' can be good and decent members of the community and that we positively contribute to society.
But when you are asked about it do not deny it, and when you discuss it, use your faith-fighting skills and the power of truthful knowledge to remove the stigma with which we are all marked. I look forward to hearing about your experiences in the struggle against the occluded.
I have little poignant or anecdotal to share in this space, but I'm glad I wrote something that made someone like you waste their time reading it. HAVE SOME.
