So, only Catholics are allowed to create videos on Youtube or anywhere else? Or, do you go to their Youtube channels and say the same thing? You don't, do you? Ever heard of "Freedom of Speech"? Perhaps you think it only applies to you and other Catholics, right? No, it applies to everyone (where applicable). If you do not like it, then here's what you do: don't watch it. Don't read literature on it. See how easy that is? Of course not. You have to watch the stuff (if you in fact did), you have to read the material (if you in fact did), and then you have to tell people to go to Hell. Such a loving Christian you are.
