Is honking your car horn ever okay?

Context: I was driving in South Carolina near Charleston when a pick up truck swerved in front of my car and braked hard causing me to do the same to avoid crashing. I honked my horn as a ‘hey didn’t you see me you nearly caused a crash’ type thing. The pick up then slows down further up the road to wait for me to pass, as I do the driver throws something (it was dark so not sure what) at the passenger side of the car, taking some paint off the bodywork in the process. In the U.K. honking the horn isn’t considered particularly out of the ordinary if someone is driving dangerously.
