Because a mis-informed Christian chose to argue with me about the Bible.

 I am an Agnostic. That means I don't deny the existence of a higher power (God, if you wish), but I don't support it either. I see no evidence and no reason to suspect there is a Higher Power. However, I see no reason to deny it's existence either.

 Let me take that a step further; I see nothing in the Universe (which includes You and I and the little barking puppy down the street) that can only be explained by the existence of this Higher Power. Life is inevitable; place the proper chemicals together and apply heat and life occurs. No divine intervention is required. That does not mean there wasn't any, just that it is not needed.

 It behooves me to let You believe whatever you wish, without calling you names or saying you're a fool for believing it. I hold others to that same standard. But, I will call out logical fallacies when they are used as proof in any circumstance, including religious proselytizing (oh, look it up). 

I do not ask that you believe as I do, I only ask that you do not shove your religion down my throat. That includes telling me to have a "blessed day". I don't wish to have a day like that, it is not in my belief system. However, I appreciate that you feel that I deserve to have one, based on your beliefs; Thank You.

What I truly resent is folks who insist that this is a "Christian" country and then cheer the caging of children, deny the FACT of climate change and support the lies and outright evil coming from some of our leaders. Folks who claim to be Christian and then cheat on their spouse. Christians who misquote the Bible (that really pisses me off).
I hold all religious people to this same standard; do not misquote the Bible, the Quran or the Torah. Do not twists the meanings of these sacred texts to suit your twisted ideas.

Things Christians should know about the Bible (but probably don't):

The Bible was written in Aramaic and Hebrew, not English. It was translated into Greek and then Latin sometime later. The current English version is based on the King James version (early 1600s) which expunged many references that King James and his Bishops didn't like; notably many about women.

The Roman Emperor Constantine convened The Council of Nicaea (AD 325) and decided what books would be henceforth included in the Bible. It was at this council that Christ was declared to be divine. Before that he was a Human.
