Edit: FUUUUUUUU off-topicers. When I started this I thought "yeah one or two paragraphs, no biggie." ._.
That paragraph doesn't make much sense considering all you just said prior to that point (and all in response to a little jab of mine?) Anyway, I don't particularly take kindly to an attack on my person, but to keep religion itself out of the thread and because you brought it up, I will indulge and focus my response on me.
I come from a religious background. My mother was deeply religious and my father was religious on a near-fanatical level. I grew up listening to God-inspired morality lectures and Bible stories after every dinner of my childhood and early adolescence. These lectures usually lasted for an hour but sometimes for upward of three. I was imbued in religion and believed it all, for a time. I used to read the Bible and I would pray before every meal and before going to sleep. At that point, I was already more familiar with religion than most people my age, though not exactly in a healthy way.
I started having doubts when I was around the age of 14, but it was very difficult because of all the guilt that came with it. I wondered if I would go to hell for doubting. I thought I must have been a bad person. Leaving a religion can be extremely scary for a person who was raised in an environment where such a thing was not only inadmissible, but also evil.
Come the age of 15, I was becoming more and more certain that most of religion was untrue. However, I was extremely moderate about it. But also more comfortable with my disbelief. My father wouldn't hear of it, though - he yelled at me that if I didn't believe in God, I couldn't be a good person. Thankfully for me, reason defeated emotion.
My disbelief increased over time and reached a peak around the age of 19 or 20, when I finally stopped giving religion and other superstitions any sort of breathing room. I used to say things like "Religion isn't inherently bad, it's people who are bad," which I still hear all the time from moderate Christians or recent atheists. Now I know that it was simple bullsh*t I told myself to avoid dissonance and conflict while in a transition phase between belief and disbelief. You said this:
And delivered the line as though it would be an unreasonable thing to have a grudge with all things irrational. But I do take issue with all things irrational, and I see no problem with that. But I digress.
I'm offended that you would suggest I'm just another run-of-the-mill ignorant person who happens to have an opinion about something for no particular reason of his own. I've always been a person eager to learn. I've constantly been reading books since the age of 5. I used to always annoy adults as a pre-adolescent boy because I thought their conversations were far more interesting than those with people my age. I study philosophy and I'm even taking a Bible course right now, purely as an elective because even though my opinions on the subject of religion are firm, I'm not ignorant enough to think that I know it all. I've read books on the god debate and have watched countless debates and interviews on the subject. I've gone out of my way to have discussions with people at my university to talk about their beliefs, both Christian and Muslim.
So spare me the comments about how I'm "supposed to be the smart guy" and only have a "vague understanding" of the subject. The majority of the people on this planet don't even care about the subject enough to have bothered doing the research that I have.
