There's a bunch of Catholic bloggers whining about comments lately. I find that annoying. If you don't like what people have to say either stop blogging or set your blog to no comments allowed or just delete the comment. End of problem. Now, on the other side, folks when you visit most blogs it's like visiting someones home. With this in mind, one should always behave nicely when commenting at a mommy blog, a priest or consecrated person's blog or any personal blog. There is one well known priest who blogs (NO IT IS NOT FR. Z. so DON'T EVEN GO THERE) whom I can't bear so I do not read his blog at all. That keeps me from offending our Lord and writing what I really think about some of his posts.
As for professional layperson bloggers who dare to present themselves as Catholic experts who are qualified to teach and advise, yes, you betcha they are fair game. Especially if they insinuate that anyone who isn't their sychophant is an idiot or a barbarian. No layperson who makes their living off of the Church is too high and mighty to be questioned. If they can't take the heat they should leave the arena instead of being big ole crybabies. If you do comment on something that seems wrong please be polite and I beg you -- don't write in text-speak. Do not attack the pope. Attack the pope and I'm steering clear of you, period. Don't go for the jugular vein by calling the blogger or other commenters homosexuals (yeah, I've seen that) and damning people to hell because they don't agree with you is wrong and dangerous to your own soul.
I am not saying that we who comment on Catholic blogs have to talk like old spinster Aunt Pitty Pat espeacially when crap is being spoken about the Faith or in the name of Catholicism but you can tell someone that they are wrong without going mafioso on them. Okay?
