I think you are trying, with a measure of deviousness, to intimidate the good priest about what he said regarding caste being a sin, and also subtly trying to discourage other priests etc from coming forward about caste with your implied claim that you have Church interests most at heart and want to save it from those demons from across the seas who are asking searching questions.
As for all those guys outside Goa "who think they are smart" as you say, they don't think so Gilbert, as they know they are! You have been unable to take them on with a cogent/persuasive argument in a single instance as far as I can tell. And, incidentally, you are from outside Goa too, but at least, you do implicitly recognise/concede that you are not one of the smart ones!
When in a hole Gilbert, the most important rule is to stop digging!
