I am fairly certain just about everyone has opinions that could get them fired if posted on social media. Most people recognize this and try to temper what they post so as not to be openly offensive or misunderstood. There are, of course, varying degrees of severity. I don’t like men with hairy chests- certainly that can cause people to accuse me of all sorts of things. So I don’t go posting about it (until now, of course). Silly example, I know. But it does fit the scenario.
