E.g. is calling someone a monkey (as was allegedly done by Harbhajan Singh to Andrew Symonds) racism and hence unacceptable? Is questioning some cricketer's wifes' / sisters' promiscuity acceptable just because it is part of some country's players aggressive upbringing?
Who draws the line in such circumstances? Are they umpires? Players who run to officials? Or the match referee? And who constitutes what is acceptable over what is not?
