Gonna disagree with you here Matt. I don't think you can equate public forums to real life experiences. There is something fundamentally different about posting words/ thoughts online, behind a computer screen and username, as opposed to interacting with people in person, seeing them face to face, etc. I am going to say that these forums, yours included, are the best thing of a bad situation. If the Church was flourishing (and when She flourishes again), I would not be surprised to see legitimate restrictions placed on the people from using forums.
The good fight isn't about knowing all and being right on the current 'positions'. Its about establishing a relationship with our Blessed Lord through his blessed mother. I think that people who are humble enough to realize that they are, as you say, "unable to handle a discussion fora like Cathinfo', are probably moved by the Holy Ghost. They have probably engaged in the sins you speak of (unjust anger, lack of charity, etc), and are following the advice of Our Blessed Lord in the Gospels by cutting off that which leads them to sin.
I am not saying there is no place for these forums. I'm saying they're probably doing more than they they ought to. There is more that goes on than just, 'discussing the subjects'.
I've been contemplating myself whether to post here or not. I've decided I'm not going to cut myself off completely, because there are obvious benefits this forum (specifically) provides. And there is nothing like a dose of TradCat comradery after bombardment 'in the world', sure. But more often than not (and I may be speaking for myself only, but I think this is a valid and objective assessment for most), there is unprofitable and uncharitable discourse. Its no one's particular fault, because we're taught to fight for the Truth. But the particular crisis in the Church today can be, and is, split a thousand different ways, and that leads to a thousand different disagreements and, potentially, a thousand different arguments. Anyways, I think you see where I'm going with this. We're dealing with the Marines of the Church Militant here (I'm saying this as one who served in the Air Force- don't tell my friends). Our love of Truth, as found in Theology and the Sacred Tradition of our Beautiful Church is only matched by our willingness to stand up for that Truth; without strong authority, a gang of marines, without their sergeant to corral them, will inevitably eat itself from the inside out with plenty fist fights and brawls.
Pray for me!
