Your logic escapes me. It is OK to urinate on her grave, but spitting on her is not appropriate. When she is in the ground, Fonda won't experience such gestures of contempt. Giving her a picture of a friend who died in Vietnam and lecturing her is another meaningless act, which has no real effect. I doubt if you could even get enough face time to do it and the picture would have been thrown into the garbage by her security detail.
Woulda, coulda, shoulda. Mr. Smith did express himself and for many like us the utter comtempt we have for this POS. It was a simple, direct gesture which inflicted no injury--just comtempt. Fonda got the message.
Again, I'll say it. He and others earned the right. I guess it is hyperbole. I wouldn't really urinate on someone's grave. And I certainly wouldn't spit in someone's face. I am glad he will not be charged, and I hope he was able to release his years of frustration and anger with the traitorous *itch.
