Nonsense.
I've been a FReeper for going on ten years now, both as a Catholic and as a Protestant; I know what I see. The anti-Catholics attack everything we hold dear and trust in excepting the Bible because they have a measure of respect for it.
On the other hand, our responses are muted because we are loathe to attack the Bible, or their superstitious misuse of it.
While I realize you could be referring to ANY derision being too much, rhetorically painting a tit-for-tat scenario is "turning the other cheek" to those who will "turn and rend."
In all seriousness, what are we to do when a brother tears and rends?
