Porpoises do have sophisticated social networks. I would not call it an advanced civilization. There is a high degree of tolerance for each other, and for other species, which is one of the first steps toward civilization. This is why there are theories that dogs actually provided the model for humans to civilize. There are fossil records which show human brain size decreasing, and jaws getting smaller (all signs of domestication), right around the time that humans started interacted with dogs.
But back to the point, there is a trend toward an ever expanding definition of what constitutes a civil right. There was some controversial police activity in San Diego, when I was there. The City Attorney decided to prosecute individuals who were at a private sex party. The result was a lot of publicity, and the City Attorney was scolded by the jury for raiding the party, and bringing the charges. This then led to public meetings, attended by the Chief of Police, and representatives of the City Attorney’s Office, with members of the public, in a town hall forum.
I attended once of these meetings, out of curiosity, and I was surprised by some of the statements made. There were two who were particularly memorable. One was a man who stood up to demand that the City create, or designate, a sex park, where public sex could take place. Another man, whom I later learned had been imprisoned for some of his behaviors, stood up and made a very eloquent statement about government interference in private lives. I was impressed by the diversity of what individuals took to be their “civil rights”.
We see from old movies and television, that the standards for denigration of one group of people over another, for the purpose of comedy has changed. Also, with modern transportation, and communications, our society is as diverse as ever, and will continue to diversify further. The divergent interests of various individuals and groups are seen more and more as civil rights, not the be imposed upon, or limited, by the state.
This is a challenge, for someone who holds that there is a static moral code. I suspect that, more and more, what was once accepted as “mainstream” thinking, which was uniform in our country, will be regarded as unrealistic or quaint, due to the ever increasing diversity of our democratic population.
