In this case, the "somebody, somewhere" is thousands of people across this nation and likely many of the athletes Vidmar would represent. Let's get something straight here, Vidmar didn't just express a view, he participated in protests and gave money to fund Proposition 8. He openly supported legislation that would keep people from being able to marry the person they love. From your post, I don't get the sense that you will ever have to go out of the state you live in to get married, had to cross a picket line to get a marriage licence, or watch your loved suffer from an illness because they can't work and your insurance doesn't cover a same sex marriage. If you ever did have to go through these things, and I would hope that you did not, you might not find Vidmar to be demonized.
So, it's shameful for Weir and Hersh to express their opinions on the situation, but Vidmar can say any negative thing he wants about gay marriage...and no one should question it? That's not hypocritical at all.
Bottom line for me is that he is supporting discrimination. A person who is publicly supporting discrimination should not be in charge of anything having to do with the Olympics.
