What to do

[mrmpa]

I went to a flea market today, first time in probably 4 years. I was walking down an aisle, when one vendor began yelling across to another vendor, "we can't burn their fucking korans, but they can burn our flag." They went back and forth for probably 20 seconds, when I realized walking toward me were 3 Muslim women. This banter by the vendors I understood now, was to harass these women. As I walked by these women, I said "I'm sorry you had to hear that."

What the hell should I do, when I hear this crap from people? What do you do when you hear this crap? I wonder if something is said to these idiots, could it get physical? Help me out here for the next time I hear something like this, and there will be another time, unfortunately.
