Not that you would understand, but none of the 12 disciples or Jesus himself ever asked you to denigrate any other religion. You are ofcourse free to quote from 'Old Testament' and put your own spin on it.
So point being respect others and be respected OR Behave the way you have and be treated the same way back.
"it will be meted out to you the same way you mete it out to others."......I am sure you read it somewhere.
