To answer your questions
- Yes. John MacArthur for example. Ken Silva another.
- Seminary, westiminster Confession of Faith and any other Protestant writings and teachings out of the reformation. Error is passed on to each generation.
- Yes. But anticatholicism will be here as long as there are those who are not catholic.
Protestantism is rife with anticatholicism. Most of it is below the surface or hidden within doctrines etc. Protestants continually compare themselves to Catholics. Usually in justification of their beliefs, especially those beliefs that are contrary to Church, Traditional or Scriptural teaching.
When I was a Protestant, I do not remember any Catholic coming up to me brazenly claiming what I believed was wrong. In my Baptist Seminary, we were taught how to reason with Catholics from the scripture to enlighten them to their errors. I remember one call on evangelism, we had to give weekly “reports” on our efforts to spread the gospel. Those who engaged Catholics were seen in an elevated manner than those who engaged methodists or even pagans. My professor, Dr. Green, would almost become giddy when a student related yet another encounter with a Catholic. (we got extra points for Catholics

, other protestants and the orthodox not as prized.)
But we are not alone. The SBC is on a witch hunt for calvinists within their ranks. That is why the SBC has been relatively quiet on the anticatholic front. Need some housecleaning done first.
I was a calvinist SBC pastor. Next to catholics, calvinist are just as “loved”.
My advice. Know your faith. Laugh when ignorant anti-catholics start telling their whoppers and if they are ready to listen, correct their errors. They probably will not listen, but those around will be.
I “debated” a rabid anti-catholic who was ranting in the largest baptist church in Pensacola. My youngest daughter was there for soccer practice. I reached my popeye moment, “stood all I can, can’t stand no more”. I laughed at is ignorance, lack of biblically understanding, he was ranting Paul and Jesus taught a different gospel from the Apostles.

, laugh at him so more. Countered every point, with humor, wit and pointed retorts when needed. My final comment to him, was who vetted your beliefs…which pastor, church, denomination. Of course he said the Holy Spirit helped him understand the scriptures. So how did he know it was the Holy Spirit? By what authority and why should I listen to you and not 2000 years of Catholic and Church teaching. I said, “just who do you think you are…I think you are antichrist…you preach a different gospel.” With that he stormed off. And the Baptist clapped. When they found out I was catholic, most eased off. Many stayed, none challenged me. Those who stayed were interested in what a catholic thought and believed by talking to a catholic and not just listening to a preacher tell them what a Catholic thought or believed.
Note, most protestants get their theology and beliefs from the preacher. They do not study and if they do, very few read outside their beliefs and denomination. Sadly, so do most catholics.
