With all due respect, I think you're missing something here, seacookie.
While I'm not even going to voice my opinion as regards whether or not the fellow should have been disembarked. What I am going to say relative to this incident is, if developement occurred as related, why wasn't something done to the instigator who kept insisting the American speak English? Why didn't one of the table employees or pit bosses themselves turn to the Russian and tell him in English (his obvious language of preference) that no passenger was restricted in using any language he so chose as long as the person with whom he was communicating spoke the same language.
It was actually the fault of the ship's staff that the incident even continued to it's regrettable conclusion.
