Many Protestants literally spend their lives making up stuff 'that Catholics believe' only to be completely wrong. They then don't ponder why it is that they have the need to focus on making up stuff about Catholicism. Rather, they simply move on the next lie. When a movement bases itself on attacking and lying about another movement it will not last long.
Throughout the thread the Prots here assume that the Catholics should have to 'disprove' their accusations. It's silly but ultimately when people go about making up things about other people they tend to move into silly territory. Looking back I reviewed a post where some Prot here decided to make some silly accusation and I asked for proof and he shifted and just moved onto the next accusation. Weak.
On my profile you will find a set of links under “Easter 2008 Celebration”. I had a lot of fun with that. The psychology of anti-Catholic crowd is just like you describe, but I also had several very serious people making serious responses and asking questions in the spirit of goodwill, some times on the threads and some times privately. I think more people realize that the Protestant world is in a theological and ecclesial crisis than we know.
My wife converted this Easter. She couldn’t be happier.
It’s like the funny story about someone seeing a donation box in front of an altar and calling it sacrifices and magic.
