It wasnt that they were rowdy.It was the specifics of what they were saying.
Oh, so you were "offended" by what they were saying? You sound like a self-righteous asshole.
Hey, there have been times that I have told people who were bullying others to knock it off. Even have stopped a couple of fights. Had some poor dude walking down the street with his girlfriend get jumped by two dudes at the base of my driveway. Went out there, told them to knock it off, and that the cops were being called, but that was because they were kicking the dude on the ground and that is assault in my eyes.
I personally can't stand those who think it's okay to berate others in public just because they look different.
