I can answer that one!
The "attacks" usually come from the Romanists, when confronted with clear Scripture refuting the heresies and abominations of the largest cult in the history of the world. There are not normally ANY personal attacks as they are not allowed.
It hurts when you see that anything you have been taught is a lie. When it is consolidated into a realization that you cannot refute with anything except claims of "tradition", not finding any of those "traditions" based in the Word of God, then it is normal to lash out. We see the Romanists doing that with cries of foul and claims of personal attacks!
But, it is incumbent of Christians to confront lies and half-truths which may hinder a non-believer from finding the Truth of God's economy. It boils down to the simplest of things. We have a relationship with God based on faith. Nothing required but faith that He is in control, not us.
Paul's letter to Timothy reveals much along that vein...
1 Timothy 4: ... 4 The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons. 2 Such teachings come through hypocritical liars, whose consciences have been seared as with a hot iron. 3 They forbid people to marry and order them to abstain from certain foods, which God created to be received with thanksgiving by those who believe and who know the truth. 4 For everything God created is good, and nothing is to be rejected if it is received with thanksgiving, 5 because it is consecrated by the word of God and prayer.
6 If you point these things out to the brothers and sisters, you will be a good minister of Christ Jesus, nourished on the truths of the faith and of the good teaching that you have followed. 7 Have nothing to do with godless myths and old wives’ tales; rather, train yourself to be godly. 8 For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come.
Believe me when I say that Catholics see the clear meaning of Scripture confirming, not refuting, our beliefs. Do not confuse your own private interpretations of the Bible with Scripture itself.
