Little Punk Skateboarder

Now, I've always been an open-minded kind of gal but I'm about done with teenagers, especially the skateboarding and bicycling types. About 2 weeks ago, I was driving to work and this little punk on a bike comes out from the sidewalk and cuts straight across the street, right in front of my car (I had a green light). So I honk and the SOB flips me off. Flipped ME off. For riding his bike in front of my car. Yes. So, I yelled, "Get out of the road!" and he yells, "FUCK YOU, CUNT!". So I keep going, wishing I had a projectile in the car for me to bounce off of the back of his head.

Today, driving home from work, I'm coming to the intersection of Newton Street and River Street and there's this little fucker in the right lane on a skateboard going down the hill. So he crosses into the oncoming traffic lane and goes out right into the middle of my lane (about 10 feet off of my bumper). I SLAMMED on the brakes and get on my horn and yell (again) "GET OUT OF THE ROAD". So he yells back "FUCK YOU" and flips me off with BOTH hands. Yes, that's right, I got flipped off because I didn't run him over. So I pass him and he's still skateboarding down the street STILL flipping me off. So... I slammed on the brakes and come to a complete stop in traffic and say, "You know it will be natural selection when your sorry ass gets run over, you dumb fuck!" and then I proceed home.

So here's my Karmic question. Why did I get flipped off and called ??? names for not taking these dregs of society out of the gene pool? I did the right thing (i.e., not killing them) and they say "FUCK YOU" to me and call me a cunt. For not killing them. So, what, should I have run them over and then they'd be happy? No, I'd have bad Karma for killing them when I could have prevented it. UGH. Next time, I'm going to just get out of the car and beat them with a tire iron. I think it'd make me feel better.
