However, when a speaker or writer expressly or impliedly calls on other individuals or society in general to believe and/or act on an opinion

That is the point. I didn't. I had and still have no intention of getting anyone to believe or act on my opinions. This, as I have often said, is a trivial site dedicated to folk music. It is not important and even less influential. If I wanted anyone to believe or act on anything but folk music, it would not be on here.

I am sure Steve well understands the point I was putting across and I am not going to go through it again here as it belongs on the other tread. Whatever the case I still contend that an unexplained opinion can still be as valid as one where the details are made clear. What is more, there are some people who will use the minutiae to nit pick where the overall meaning is obvious. Of course he is right about prejudice and bigotry and opinions based on those should be challenged. I am prejudiced against the mainstream media, I make no secret of that. Just as I am prejudiced against other bigots and hate mongers. It is a valid opinion to hold with or without explanation.
