I'm glad to hear that you didn't blindly inherit your beliefs but worked on to find out what you truly believe in. However, did you believe in Islam because the idea of a God is logical or the idea of the ISLAMIC God? I wouldn't deny or confirm the existence of a god myself, but to me, I doubt it's going to be a god of the religions I've witnessed so far. Now I could read huge philosophical essays written by both atheist philosophers and Islamic ones and be totally confused, or I could just follow what makes sense to me. When I look at Islam I see things like hatred and threats of eternal punishment of two people just because they're in love and want to live their life like any normal couple, just because they happened to be both of the same gender and born to be attracted to each other. I see "death penalty for apostasy" on one hand, and then "freedom of belief" on the other. Such "rules" just make me believe that the religion is un-godly and couldn't have been sent by an all-mighty god of perfection.
I'd rather just live my life under my own rules and try to be as kind to others as I can. If a god would want to punish me for that, then so be it.
Well, in short, I've been considering myself an atheist for about 5 months now. But I've been having doubts for at least 4 years. I felt that a huge part of why I followed the religion that I did, was that I was just told to ever since I was young. I wasn't exposed to other view points. As I grew up I began wondering why nothing made sense to me, there simply wasn't enough evidence, I explored other view points and decided to follow whichever seemed the most logical to me. I wouldn't have a problem with religious people if they didn't try to force their beliefs on me, if they didn't arrest/imprison/discriminate against people who just want to believe in what makes to them, as is the case in my country. Contradicting themselves when they say their religion calls for freedom of belief. Sorry if I've written a lot, but if I could get my viewpoint to at least one person to believe that non-believers aren't evil people I'd feel great.
