I got unceremoniously uninvited from a caucus thread one time years back for that exact thing.
It was about a priest who lost his job for standing his ground about something he believed and I had a lot of respect and admiration for that kind of character.
My posts were positive and I was booted and told by the Catholics that it wasn't because of the content of my posts, but it was because of who I was.
So they don't even allow others the opportunity to agree with them and yet complain that all we do is criticize.
You can't win with some folks.
