We need to become a civil society in the precise meaning of the term. So we should stop specifically identifying people by their personal affiliations and use a code known to all but not personal. So, for example, the group that the following person is a member of, whatever it might be, would be called, let us say, 18c.

Then you could go around saying that you are disgusted by 18c and the kind of things they do and no one would be offended any more.
