Well the simple answer to "why the hate" is and can only be some kind of issue with the "hater" themselves. Whether it is jealousy, regret, transference of anger at their own perceived failures (this is a classic one - to try and pin someone else as a greater failure than you perceive yourself which makes you feel better about it) - , not one of these guys took anything from any "hater", be it time, money, energy - nothing.
Therefore the hate has nothing to do with Tinman Elite, it really doesn't.
You "hate" TME because the runners aren't as elite as you think they are? It doesn't what you think. You hate them because of social media? Don't be part of social media. You hate them because of what went down with their coach? I guarantee there are about 20 people on earth that truly know what happened and the odds are you aren't one of them.
If you truly hate or even really give a f--k what these guys do with their lives you need some more productive interests in your life because you are pretty pathetic.
