There's a lot of hyperbole in this thread. If you're upset about Melky joining the Sox, then I commend you and also am sorry for you because it must be tough to watch any entertainment in today's world. It is very hard to find actors, actresses, athletes, that haven't cheated in some way. Drugs, plastic surgery, infidelity, etc. must quickly narrow the options you have in the world. This isn't to say that you are wrong.
As for me, I love the Sox. They are a great form of entertainment for me. So now I root for Melky because he wears a Sox uniform. It's really that simple.
