Maybe you should actually read the Bible before you bash it. I edited your post to fix some inaccuracies:
religion will teach you how to be a better person, we can't compare all religion where are good it's back to your self. where you faith believe in Buddhism, Islam, Christianity, Hinduism, Catholicism, atheists, Unreligious. so i never think Christianity is Poison or other religion is Poison, in my view all religion is same.
Religion does
not teach you to be a better person...
Religion teaches you to own slaves (Slavery in the bible is nothing like American or modern slavery. That said Christians strongly believe slavery is wrong.),
rape women (Absolutely not! Exodus 20:13), murder homosexuals (Absolutely not! Exodus 20:13), murder witches (Absolutely not! Exodus 20:13), murder your own children (Absolutely not! You have misinterpreted the story by a long shot), etc...
Basically, religion teaches you to be a
hateful (John 4:20, Proverbs 4:12)
narcissistic bigot (Proverbs 29:23, James 4:6), who thinks
God loves you more than other people (yes, he does love us more than anyone on earth: For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.)...
If you managed to learn something good from religion, you did [
not do] that on your own...
please do not give religion credit for your own deeds "for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus...
Then what becomes of our boasting? It is excluded."
