It's unacceptable.
This new "Buster Posey" rule is a joke. It's to protect the catchers (who ironically are the only ones wearing PROTECTIVE gear) who don't know how to protect themselves.
Watch as Posey BLINDLY and RECKLESSLY turns into home plate and the "receiving" area (without even having the ball).
I am a bay area guy (A's fan) and had countless discussions with my local Giants fan friends about this (none of whom played baseball past about 9th grade).

Thank God this is an "experimental" rule this year.
