Yes, my post to you was sarcasm.
Unfortunately, no, many Catholics do not see fundamentalists as brothers and sisters but as stupid, bigoted, and violent (about how Jews regarded Catholics in the Middle Ages). Catholics on this forum have made sneering references to "Billy Bob's Glory Barn" and called Fundamentalists such things as "Cletus" and "brain-dead bibliolators" (actually, the guy who called them "Cletus" wasn't Catholic but claimed to be pro-Catholic). A prominent Fundamentalist minister has been compared to a fat hog in the mud.
There are a few Catholics on this site who don't sneer at them. If you also do not then welcome to an extremely small club. I wish there were more of you.
