2+2 = 5
Is it right or wrong?
The answer is wrong. In this case there is right and wrong answer.
But, suppose the question was what colour is THIS
Many would say blue, but then what is THIS
Also blue? But they can't both be Blue. But it's also not wrong that they are Blue. They are shades of blue, and actually have proper names.
This is what almost all religions are like for me. They are all based on the same thing, happiness, peace, love and spirituality. So for me they are all the same colour, but only of different shades.
So how could I say any of these religions are right or wrong over the other? If I say Christianity is wrong, and Hindusim is right, given that both are about getting salvation and becoming one with god, they cannot be mutually exclusive. What does separate them are the beliefs about god and what salvation is, and for me, that is only a difference in the shade.
