I'm grateful to the Post for publishing this article because it gave us a new dimension to Fritz's story. Like a lot of obsessed people (maybe most?) he was not a nice person. He lacked empathy and he was quick to form petty grievances. It's tragic that he and his oldest son never reconciled before he died.
But what's just as interesting is the petty bickering in this thread. There is an irony here that I can't quite describe.
