Why isn’t a bigger deal being made of this?

Shawn Chacon throws his GM to the ground, and gets released without pay. Manny Ramirez pushes a club official to the ground, and it’s just Manny being Manny. I fully understand the difference in status between the two players, but that shouldn’t matter when you physically assault someone. What if you or I pushed someone at work to the ground like that? What a bunch of crap.
