So, if this person is professional at work, then you come home, and watching the news, you see a report about a neo-nazi parade, and there this person is, literally on-screen, shouting "burn the niggers*. Is that also ok?
Of course, this is an extreme example, I'm just interested in understanding where the line is, or indeed if there is one, in the minds of people who think it's ok to express any opinion without there being any consequence.
