Provide notice to the offending player to please refrain from derogatory dialog, if non-compliant, report them.
As a player we are part of a community. All sites have a policy regarding table behavior.
Does anyone think as to why?
We are all patrons of this community. We have ownership. When one misbehaves, that behavior reflects upon all of us.
We have a duty, each one of us, to correct the behavior of the bad apples. It matters as poker tries to become legitimate in the eyes of the public.
Legitimization will lead to legalization, more people playing, higher purses.
