Ahem, yes that's what I meant. Thanks, RussB.

There's also a profound difference between getting into a debate with someone who is genuinely prepared to listen and, critically, if by learning something new through the process of the conversation, to change their mind, and those who want only to lecture and persuade the other person without actually considering the possibility of changing their own minds.

The latter approach is also known as 'faith'.

Or as I think Oscar Wilde said, "a priest is a man who says the same things at eighty as he said at eighteen".
