A good post, and I agree with you. A lot of the sanctifying Travis was a media creation designed to stir up interest in the case. Some of it, in my view, came from well-meaning people who were outraged at what at happened to him -- and without meaning to do so, sort of de-humanized him by contrasting him as a paragon of sorts in comparison to Jodi. He couldn't win in either case, because no one is perfect on the one hand and he was, as you said, a consenting adult engaged in what I believe was entirely reasonable and consensual sexual behavior with a willing partner. It might have offended some people, but everyone has different standards regarding appropriate sexual expression.
The bottom line, is, of course, that Jodi did not have a right to kill him and has failed utterly to prove that she did have a reason to defend herself against him. In my mind, it does not diminish the man at all to admit that he was mortal and subject to some of the same vices and failings as every other mortal person. It does not make his death less tragic. I agree that it's past time to focus on the real issue.
