If some Protestant denominations viewed Catholics the way you say Catholics should view Protestants, they wouldn't even exist. The Assemblies of God in some places is as much as 90% ex-Catholics. I suppose Pope Francis is fine with that. He certainly has few or no kind words to say about actual Catholics trying to remain faithful.
What you're saying amounts to demanding that Catholics unilaterally disarm, and let Protestants and others poach as many Catholics as they can.
We have real disagreements, and it's dishonest to pretend that they don't matter.
Not at all. I'm saying the evangelizing efforts exerted by any Christian group would be better concentrated on the unsaved, unbelievers rather than on those who already profess Jesus Christ. There's no "unilateral" disarmament for either. Nobody "poached" me from Catholicism. I was seeking to know the truth - not just what I had been force fed - and the Lord quite miraculously revealed it to me through His word. A light in my soul went on and I knew the gospel was NOT what I had been taught. I left of my own free will with no animosity towards my previous religion. I just knew I didn't belong there anymore. For some people, maybe it's the other way. They want what they think Catholicism offers them. I don't try to poach anyone away but leave that up to the Holy Spirit.
I also don't pretend we don't have real disagreements and I am more than happy to discuss them and why I believe what I do. But it is ALWAYS going to be the Lord who changes hearts.
