I can see the guy getting wound up about what he perceived as a threat. He should have, however, backed off when he saw what was going on - as long as you were treating him with the same repect you would expect him to show you.
How big are these bogs you are talking about? As a long time coyote caller I see your set up doing far more harm than good in a calling situation. Unless these bogs are miles across I suspect you are doing far more spooking than spotting!
What I would be miffed about is why these guys didn't wait to check you out at your vehicle. Screwing up a hunt is bullcrap, pure and simple.
