Watching what you are saying is good manners whatever the topic in case someone in earshot may be offended, that has always been the case. It's when the law becomes involved over an opinion someone has voiced, not incitement to hatred or violence, not a verbal attack, just an opinion, however misguided or narrow minded, just an opinion, a dislike of a certain group of people. If that is all that is said and then to try and take legal action, we are going down a very slippery slope.
