I'm not talking about the union (which can hardly be called a joke - it's the most powerful union in sports,) but rather the many players, both current and retired, who have come to Barry's defense in a time in which he is being made a scapegoat for the sins of many. Watch what Clemens, Wagner, Jeter, Griffey, Pujols, and many others say if he makes it passed Aaron. They respect Bonds even if large segments of the fan base of their respective clubs have bought into the view of the press that he is somehow the devil incarnate. Perhaps it is because, as fellow players, they know just how widespread the problem of steroids is, or perhaps it is just because they don't let other's hysteria blind them to the best talent of this era.
With fans from other cities, I would expect them to boo Barry as they always have, but there are still those who will rise and applaud when they see greatness on the field - regardless of which uniform a player wears. If you're not one of those, ok, but I wouldn't brag about it.
btw, did anyone notice when Barry hit 715 an Umpire stopped him on his way to his position and gave him a hug in recognition of his achievement? THAT'S something I've never seen in all my 40 some years of watching this game.
