But there is absolutely nothing even remotely funny in anyone not respecting someone else's right to voice an opinion.
When we find ourselves in the position of not sharing someone's views, we should say so politely, not spit, abuse the other person and assuredly not hit him.
Whether this actually happened or not is irrelevant. The very fact that anyone could make a joke about this kind of behaviour is worrying.
Are we really living in a world where it is all rigth to abuse those we disagree with?
