Thoughts
Let me summarize your diatribe:
1) You know how to run a track better than the local owners
2) you talk trash even though you are at the back of the pack
3) you are shocked that people are competitive and that everyone doesn't get a trophy for trying
4) your son doesn't want to race, so you don't either, which is fine
5) you think spending time racing without your son is a waste of time and you want to convince all of the unwashed masses to do as you do
6) since you don't want to race anymore, you must do your best to convince others to quit also, since you know what's better
Did you try to make the local track better? Did you talk to the owner about the drug use and profanity? What did you do to make it better other than walking away?
By the way, I have waited many times in races if I have a sizable lead. I don't do it to embarrass anyone, and if the person tells me not to do that after the race, I apologize, and I don't do it again while racing with them. Simple solution.
