Defending the faith and anymosity are not synonymous. I think I can speak for many Catholics on this forum when I say that we defend on an "as attacked" basis but we don't go looking for other faiths to pull down. Our animus, if indeed it is that, is primarily directed against those who claim to be Catholic but who attack the Church from within. I think this forum bears that out.
The reason for this is that our daily lives are not directed towards Protestantism. We don't focus on it as a matter of course. Our identity is centered on the Catholic Church and it's spiritual life is sufficient for us. Methodism, Presbyterianism or Episopalianism are not a part of our raison d'etre nor do we feed off what happens within these communities.
On the other hand, Protestantism by definition, arose as a protest against certain aspects of Catholicism and so that forms a significant part of its outlook which continues today. Catholics are not protesting; you guys are and this forms a large part of your raison d'etre. This necessarily means that your focus is directed towards the object of your protest; the Catholic Church.
It goes without saying that this is not healthy and I think it helps to explain the bitterness and animosity which pervades so much of your writing. No amount of cutting and pasting Scripture can hide that.
Catholic threads outnumber Protestant threads here 10 to one. If our tone seems defensive to you, perhaps it needs to be.
"Rome has not essentially changed. Rome declared that what it said at the time of the Reformation was infallible and could not change. Declared it to be irreformible truth. Rome has not changed and precious truths of God's word are still worth upholding even at the cost of unity even at the cost of being considered "troublemakers" in the religious world. We need to guard the antithesis against the destructive error of Rome." -- Dr. Greg L. Bahnsen, THE REFORMATION, October 28, 1990. "The Reformation is dying daily in our day when the Ecumenical Movement, and other forces like unto it, wish to soften the antithesis with Rome, today. I want to assure you that it's not my pugnacious debating nature that makes me say we must exalt that antithesis and guard it. It's my love for the Lord Jesus Christ and the purity of His word.
As for "cutting and pasting Scripture," I long to do even more of it. You should try it. You might see things differently.
