If you’re asking if all the answers you see here were provided by professional apologists who came to these forums to provide all the answers and then left the rest of us to pick up where they left off, the answer is
no.
The posts you read in these forums are, for the most part, by just ordinary Catholics like you and me who have rolled up their sleeves to learn the faith on their own, debated anti-catholics and maybe got beat up a little, then rolled up their sleeves to do battle again. Anyone can learn and explain the teachings of the Faith, but they must be willing to apply themselves and take their knocks.
I don’t know of any such groupings in these forums since we all tend to act independently and speak for ourselves. We may agree with one person or another’s opinion or statement of the Faith regarding a particular question but, no, we don’t make it a point to form teams or gang up on people.
