Is it normal to feel disrespected when people you don't know lean on your car?

I've been socially awkward most of my life, so occasionally, I have to verify with others to make sure I don't reaction awkwardly to certain situations. Well today, I got through doing some work and I see a group of random men leaning on my car. On the inside, I felt disrespected, but held my composure for the most part. I should say that it wasn't about them damaging the car, but the principle behind it. I wouldn't mind if a group of friends leaned on my car, but they were random men. Am I in the wrong for being angry at them?
