I agree with you. It almost sounds as if Catholics are being accused of witchcraft. Our own little Salem witch trials, here. Sometimes our separated brethren, God bless them, are a little spooky.
I know for certain that my Baptist son in law, my Methodist daughter in law, my Jewish relatives, my non-denominational brothers, none consider Catholics to be pagan. All of us believe of Jesus that He, aa you said, “ is the second Person of the Trinity, God made man, born of a Virgin, incarnated through the overshadowing of Mary by the Holy Spirit, who suffered and died on the cross and was raised again, to ascend back to God to sit at His right hand.
“
Sorry, I should not have included my Jewish relatives as believers in Christ. They await the first coming, presently.
It has been an eye opener for me.
It explains a lot and saddens me greatly.
Yes, it is an extremely small and vitriolic subset of Protestants. It would be a mistake to attribute their views to Protestants in general.
