There isn't a Catholic church, or even a Catholic mission (and perhaps no Roman Catholics at all) in the county in which I was born and reside.
Now who is insulated?
Here is your original comment:
Most American Fundamentalist Protestants don't think about Catholicism that much (the only Catholics they see are on TV anyway)
YOU stipulated that MOST American Fundamentalist Protestants only see Catholics on TV, the situation which you describe does not hold true for most.
My apologies for attributing my own local situation with that of everyone else.
I do know for a fact that most of the Fundamentalist Protestants around here (and I assume in the whole country) don't spend a lot of time fixated on the Catholic Church (unlike British Fundamentalist Protestants like Ian Paisley, who never seems to have a thought that doesn't involve Catholicism). However, during my six years in the Church I noticed that most Catholic publications and organizations seemed convinced that Fundamentalists were absolutely fixated on converting Catholics. So I'm not the only one attributing a personal experience to others, am I?
