In any type of angling there will always be a segment of that particular faction that feel they are above it all and look down at other anglers, shore fishermen, or non fishing boaters. There are rude, crude and lewd people everywhere. I don't come in contact with any bass boaters but I come in contact frequently with saltwater boat fisherman,,,,,,,,,,,,,,,they are no better. We got guys out here with 200k boats and 1000 horsepower moving at nearly top speed almost with in yards of other boaters, with no regard or courtesy. They fish for bait with a few feet of a jettie, it's legal (illegal at a pier) but not very courteous to the shorebound guys. The list of I'm better than you" actions are uncountable.
An arsehole is an arsehole whether he/she is fishing for bass, trout or kingfish.
