"If you can use proper arguments to justify what you're saying without using childish insults then by all means I'll listen."
I think you're confusing me with another poster as there have been no childish insults from me.
Here goes my entirely logical argument.
Situation 1 - God exists and the bible is a guide for life.
God is demonstrably not good. He is not benign. The things he has done and the things he commanded be done in his name in the bible were horrific. If he exists then he his a nasty, nasty bastard. He makes Lenin and Mao look a little misguided and Kim Jong Il / Un a tiny bit vain.
The things done in his name are horrific (mother Teresa being a good example). The crusades. The papal inquisition.
My Argument
If you take the bible and god's example as a guide then you have some very warped views and many do.
Situation 2 - God doesn't exist
Well, that's easy, isn't it.
As there is not a single, tiny shred of evidence anywhere that points to him existing it seems the likely answer. The bible is full of contradictions. Some 'facts' proven incorrect (Genesis) and just general nonsense. It's implausible and the more benign parts are actually quite funny insomuch as if I told you stories like the bible you would assume I'm mad!
Situation 3 - God might exist
Maybe you ignore the evidence that a lot of the biblical stories didn't happen or the contradictions and the evil and bile and hatred and truly horrific things god did and think, maybe he's real; I'll be a christian and have faith.
Well, you shouldn't. If he's real he's a nasty bastard. Lukemia, dementia, the eye-worm (thanks for that Stephen Fry). Remember, they're 'his' creations. "All things dull and ugly, all creatures short and fat. All things rank and cancerous ..."
Then we move on to Hitler, rape, child soldiers...
I understand the logical get-out-clause of him allowing free will but that experiment's clearly failed! Maybe it's time for the omnipotent god to step in!
Maybe he isn't real and I can base my life on my own morality. I think everyone's born equal regardless of sexuality, religious persuasion or otherwise. I judge people on their merits. I want to be a good person because it benefits society. I see us all as animals who evolved along with the rest of our planet. When we die, we feed the worms and trees and the miraculous cycle begins again.
In my eyes I do better than anyone living by the gospel but that's besides the point. The only person who watches me, who keeps me safe, who sees everything and judges my worth, who knows when I could have done better and is full of pride when I show love and compassion and understanding with knowledge of my innermost thoughts is ... me!
I fervently believe that you cannot be a good 'abrahamic faith person'
(they're the three I know enough about to comment on) and a good person. Following the book of your choosing doesn't allow it.
Good people who call themselves christians etc are hypocritical by virtue of the fact that they are ignoring their scriptures. Good on them but I think it's good to point it out to them before they indoctrinate their own children.
People who do follow their scriptures think gays go to hell, rape victims need marry the rapists, women should be treated differently by society be that not going to church when menstruating or dressing modestly and all kinds of other unacceptable views. They are not good people. Well, they may have been led astray by religion but that's a separate discussion.
I think that the only possible argument I struggle to contend is that their faith can bring people comfort. However, I think that the only reason it can is because these people have already been brainwashed. I went to a well-known reasonably religious school near Brighton and realised as a first year in chapel what nonsense we were listening to. If I hadn't I can understand that I would take comfort in a god.
Good people who do so are not following their book though. They might be good people but that's because they ignore the majority of their scripture and rely on an invisible comforter.
There is my argument against religion. It has brought nothing. It poisons everything. It makes good people do evil or good people ignore the teachings and be good despite claiming their religiosity.
I think I've rambled a bit but I hope I've explained why I am a staunch anti-theist.
In the face of absolutely no evidence, why are you a christian?
Despite the atrocities that your god committed, why do you love and worship him?
How is your life better in any way thanks to your religion (and the invisible comforter argument doesn't work!)
