I'm not talking about them. I'm talking about the OP's outrage over what he considers "attempts to undermine" the RC Church, and whether he considers it equally outrageous to "undermine" it on the grounds that it's being "too liberal", or whether he saves it only for those who want to see what he considers inappropriately "liberal" changes in Church policy...
As for most Catholics being "normal members of society," I wasn't suggesting otherwise. In my experience, when "regular people" aren't being stirred up by some ranting lunatics or others, they seem to get along with each pretty well in general even when have they major differences of opinion about things they consider important.. But there are, seriously, groups of Catholics who consider the current Church leadership to be essentially heretical for what are apparently some rather significant departures from traditional positions on a number of fundamental theological subjects...
As another aside, as for JFK, yeah, he was, but that didn't stop some (not insignificant) Protestant Republicans of his day from arguing that he would owe his "true allegiance" to "Rome" instead of the US people and the Constitution...
