Brave, man, YouTube is a hot-bed for trolls. Anonymity and higher connectedness mean that the internet often boils down to a free-fire zone, especially where Catholics are targets.
Still, it’s amazing that you can put up well-presented historical facts and they’ll sooner take ammunition from less credible sources. What concerns me most is that the generation in school now turns to the net as a primary source of information - not just dissemination. It’s one thing to pull up a well-respected academic text via google books, but quite another to go to a website some schlub who sat through his church’s Sunday School and has a lot of time on his hands built.
Still, keep it up. People believe what they see and therefore it is necessary to posit clear thought against crass dribble.
