Most of them (both "mainline" and "evangelical" protestants) seem to be pretty welcoming of non-protestant Christianity and just see Catholics as "fellow Christians with some weird beliefs". I only think maybe 5% of them are the "Catholics ain't Christian and the Catholic faith is a false man-made cult" type mindset.
The problem is that quite a few "Evangelical leaders" DO express that viewpoint, and seem to make it their mission to "turn away Catholics from the error of the Catholic Church" and get us to join some fundamentalist protestant church where we can be "born again" and "saved", cuz otherwise, we're goin' to hell. They think they're saving souls.
I supposed their sincerity is admirable, but I find their tactics to be appalling. The biggest challenge to evangelicalism in Catholicism is getting people who were already raised Catholic but have fallen away to be re-evangelized, not to convince other Christians their church is scum and get them to leave it and join the Catholic Church.
The current crisis will just make low-information Catholics easy picking, unfortunately.
Finally, I think a valid point can be made that these anti-Catholic bigots can get away with preaching ANYTHING they want about the evils of Catholicism in public, but the reverse is not true. If a Catholic minister targeted any protestant church for criticism the way they bash Catholicism (for example, if some famous Catholic priest started quipping that the Methodist Church is satanic and a great lie and that all their members are damned), that would quickly be the end of his career.
What I do mind is --- well, I can't summarize it better than Claude did (pinging you, buddy):
“You Catholics are wrong because you believe X.”
“We don’t believe X.”
“Wrong again. Yes you do.”
* Aggressiveness: 100%
* Rigidity: 100%
* Openness: 0%
* Empathy: 0%
Nuff said!
I’ve been guilty myself of not treating Catholics fairly due to disagreements over doctrine and practices. However, I am working on being able to disagree without being disagreeable to the extent that is possible. I find that often I can learn things even from people with whom I fundamentally disagree about some issue.
Part of the learning process is to realize that people cannot (and should not) be coerced into their beliefs. Persuasion is good. Even fear can be a reasonable motivator to seek God and be sure about what you believe and why. But ultimately salvation is the work of God. We should seek to be obedient to Him and listen to His voice, but only He can change anyone’s heart whether they are Protestant, Catholic, Muslim, atheist, or something else.
I’m thankful we do not live in a day when various groups within Christianity are ready to burn each other at the stake over disagreements.
