Are you serious? "Anti-Catholic rants", are those any different than the "Anti-Protestant/Reformation" rants that I see day in and day out? Whole threads even! Is it a rant if the thread is disputed with reasoned arguments? If it's an "Open" thread, all bets are off, right? Gotta have thick skin, right?
I think it is sad when some people are so attached to their religion that they cannot allow another view into their realm of thought. I see that attitude far more on the Catholic side even to the point where some refuse to accept that God can even be known by another outside their religion. I see far more acceptance of Catholics by non-Catholics than the other way around. If you haven't, you could not be paying attention.
