And if they were to become atheist they would then change in personality to become loving tolerant people?All I will say, and is relevant, is that they did those things because of their religion.
That it's not so. People judge other people on their looks, beliefs, financial income etc.
Usually, except for looks, perfect strangers do not know about beliefs and financial status. Though I agree they would not treat a bum the same as they would a businessman. But if the bum was polite and the businessman rude and arrogant, it would then be a greater factor than their financial incentives.
I treat people as they treat me. Sometimes better than they treat me. Regardless of looks beliefs and finances.
