How do you deal with the owners of loose dogs that charge up to your puppy?

Owners of loose, undisciplined dogs apparently take it deeply personal when I prevent their charging dogs from "saying hi" to my 3-month old Malinois. It's always "Oh, they won't hurt him" and just now, it was "your attitude needs an adjustment, young lady." I haven't had to kick any (out of a grand total of five dogs) yet, but I can just imagine the city-wide outcry that would follow if I dared to use anything at all beyond body language. These have all been full-sized or full-sized plus obese dogs, by the way--four labs and something really big, ugly and curly, not a single owner raising anything but their voice, and that at me, not at their precious dogs. The "in training" line, given as politely as I can, was what got me advised to adjust my attitude. I'm a hoodlum for using a leash, apparently. This happens where I live. In town. I don't do dog parks.

How do you cover your butt in the event of some owner reporting you? Especially when it's America's Favorite Breed vs. Me.
