How has Saint Paul been "trashed"?
Is the understanding that Paul's epistles are commentary on the Gospels and not the other way around somehow trashing Paul?
Do you deny that Protestant theology relies heavily on Paul's epistles?
Are you aware that Saint Peter warned that Paul's epistles were difficult to understand and misinterpretation of them was destructive?
Besides the fact that Paul is being pitted against Peter and James? I've seen many Romanists on this board claim that Paul was not trinitarian and write him off because they believed so.

No, if by that one means that Paul's epistles are directly responding to the four books that is not trashing Paul that's just an ignorant statement since Paul was not writing in response to those books but rather his epistles are for the most part letters to churches concerning different circumstances within those churches.
Do you deny that Protestant theology relies heavily on Paul's epistles?
Of course not. Since Paul has the most books of the New Testament it's hardly a strange occurrence that Paul's teachings would occupy a large portion of doctrine. It's also funny that the Romanists claim to have determined the Bible (God is only a secondary actor in this decision) yet are so dismissive of much of it's contents. But what I find extremely humorous is reading posts by Romanists claiming the Reformational doctrine of Scripture interpreting Scripture when it is the Romanists who want to pick and choose which books should be weighted more heavily.
Westminster Catechism: I.9. The infallible rule of interpretation of Scripture is the Scripture itself: and therefore, when there is a question about the true and full sense of any Scripture (which is not manifold, but one), it must be searched and known by other places that speak more clearly (2 Pe. 1:20-21 Acts 15:15-16)

Westminster Catechism: I.7. All things in Scripture are not alike plain in themselves, nor alike clear unto all (2 Pe. 3:16): yet those things which are necessary to be known, believed, and observed for salvation are so clearly propounded, and opened in some place of Scripture or other, that not only the learned, but the unlearned, in a due use of the ordinary means, may attain unto a sufficient understanding of them (Ps. 119:105, 130)
