I'm an agnostic deist. Which is pretty much almost the same thing as atheist pantheist, when you think about it...
To me, critical thinking is that you don't hold anything "sacred", you don't have anything that you're not willing to question.
Example. Your parents raise you as a christian (or muslim, or hindu, or buddhist) and teach you all their religious beliefs. Most children believe what their parents teach them. After all, to a child, his parents are the whole world to him (or her).
At some point, a child may develop critical thinking skills. This doesn't happen automatically. They need to be encouraged by proper education. When a child learns to think critically, he will question all the things he has held as "truths" just because his parents have taught him so, and measures them up against evidence. If the beliefs he has been taught contradict the evidence he observes and learns, he will discard those beliefs.
And
that is what thinking critically is all about. It can be very scary, because if your beliefs don't hold water, you'll have to rethink your whole worldview. It's very comforting to have something you can believe in blindly. It's like a comforting blanket. But at some point, most children throw away their blankets and grow up to be wholesome individuals, who can think for themselves and need no security blankets.
I don't have anything against religion, per se. To me, religion is a personal issue, everyone can have whatever opinions about it they wish to have. But when people start pushing religion to others,
and even worse, indoctrinating innocent children with dogmatic beliefs that contradict all the scientifical evidence we have discovered during the last 200 years... that I have a
problem with. There's nothing I consider more evil than lying to a child, deliberately twisting the truth because the truth doesn't fit your preconceived ideas about the universe.
Newsflash to all religious fundamentalists,
the reality doesn't change just because you believe it to be something that it's not. We can observe the world and gather evidence about it, and if they happen to not match a text that was written 2000 years ago... then it's time to discard those texts, at least as something describing the real world. Want to consider religious texts as metaphors for life? No problem. Want to consider religious texts as something that describes how the universe actually works?
Fail.All young-earth creationists who home-school their children and outright lie to them about everything that we, the human race, have learned during the last 200 years, should be prosecuted as criminals and their children should be taken away. Everybody should have a right to proper education, and everybody should have the right to choose what they believe in, without their parents indoctrinating them with all kinds of bullshit.
We have no evidence for or against the existence of god. That much is true. But we do have evidence against a lot of things the bible claims. Therefore, if you have to believe in the christian god, you should believe in god but discard all that stupid stuff in the bible about the world being created in 6 days which is obviously false, or the whole world being flooded in 40 days, or the world being flat... which are both very obviously false.
There's no reason why you can't believe in god but simply not let your belief intrude on the area of science. All evidence says that if there is a god, it does not interact directly with the universe we live in.
Personally, I choose to not have an opinion about the existence of god. I don't claim god to be nonexistent, but I don't take one's existence for granted either. If there is a god, I think it is more an abstract entity, and doesn't care one bit whether you believe in it or not.
If you own an ant farm.. do you care if the ants believe that you exist or not?
