I think your analysis of the BIBLE is flawed.
Does God tell you to only love your neighbors that believe in your faith? NO! He tells you to love all. And don't judge, because that is NOT your place, nor your power.
Muslims, Jews, Hindu, Christians.
They promote peace. Not violence.
And where in the Bible does it give you the right to talk badly about others that you know nothing about?
If I masterbate...does that mean I'm a bad person? No.
If I go to various churchs/temples and as such to LEARN, am I a bad person? No.
It is YOUR vision that is flawed. Not mine.
