Certainly. To simply discuss these apparently-atrocious teachings/people.
You must really hate them.
While I disagree with some Catholic beliefs, I hold no animosity to them or their history. I would rather just deal with the here and now and try to share different points of view regarding some of their beliefs. And, I have it as one major goal to change a mind or two. I certainly expect any one or more of those folks to do the same in my direction and for the same reason.
On a side note, I have recently seen somebody say (somewhere) that nobody is going to change their minds, what with the endless debating over the same topics again and again. Then why come here?
I have three goals here: 1) to learn stuff I don't presently know, even to have my mind changed about something I think I know the truth of. It has happened before. 2) to teach someone, or even change somebody else's mind where I think my point of view can be a benefit. 3) to enjoy the camaraderie that exists here.
