From a religious perspective, what are you not anymore, and why?
I'm no longer a Christian because I was able to see that the religion was false, and so left it. As I continued learning, eventually, I evolved into a humanist, and then an anti-theist, by which I mean somebody who considers Christianity (and possibly Islam) a net harm to the world, but my perspective is American. I would likely not be nearly as opposed to organized, politicized religion were I raised in one of the other Western democracies.
Is it fair for one to judge a religion based on it's adherents?
What else can you judge it by? How do you judge a university or a recommended weight loss diet if not by its fruit?
You've heard the phrase 'true Christian,' which means a good Christian by Christian standards. They mean to look to the book. But what value is that to an outsider? Look at what people who practice that religion actually do to understand what a true Christian is. It's an actual Christian - the man on the street.
We all need something to lean on.
I think I hear a Bill Withers song coming on.
I remain a Christian because of critical thinking
That's an interesting comment. I say the opposite about myself.
Critical thought is prescribed and proscribed like addition. It is a set of rules that, if followed faithfully takes one from evidence to sound conclusions (or addends to correct sums). The point is that if two people start from the same premises and apply the same rules, they must end up in the same place. If they don't - if one get the sum 11780 and the other 11870, at least one must be wrong. Likewise with critical thought. If two people come to mutually exclusive conclusions, at least one isn't as critical a thinker as he or she claims to be.
Since I claim that I'm not a Christian because I'm a critical thinker, at least one of us didn't do it correctly.
The lack of belief in a god/s. Either through absolutely denying that a God exists at all or, as an agnostic atheist, saying that we cannot know if a god/s exists or not, therefore we cannot come to any conclusions about them because we do not have enough supporting evidence.
That's my definition of atheist as well, although I leave out the denying versus agnostic part and stop at having no god belief, since those don't define atheism, and neither is essential to being atheist.
I don't consider my atheism a world view. It's not even a belief. It is the result of two beliefs - skepticism (nothing should be believed on faith) and empiricism (there is insufficient evidence to support a god belief) - but no other belief derives from that conclusion besides there being no point in going to churches, tithing, praying, or reading holy books. My worldview is (atheistic) humanism. Its metaphysics is naturalistic (godless), its epistemology is skeptical, empirical, and rational, and its ethics is based in human moral intuition, not received dos and don'ts. That's a worldview, not just having no god belief. I also have no leprechaun or vampire belief, and also don't consider those worldviews.
