This is not the place to discuss scientific results outside audio engineering and related fields. However, I do agree with the opening sentiment that science is not a democracy and that opinions cannot take the place of facts. So yes, people are entitled to have their own opinions whether they like Bach or the Stones, but not to their own facts, even if there can sometimes be disagreement about those facts. And yes, therefore, I think there is a similarity between creationists and audio subjectivists who claim they are entitled to 'opinions' about what are or should be facts.
In any case, the earth really is a lot older than 6000 years or whatever, and humans did indeed develop very slowly into what they are now - and continue to change, to be sure.
As for polititical pressure on universities in some conservative states in the US, I do indeed see quite a bit of that, and it is troubling. I must admit that there is also some on the other side of the political spectrum and that is equally disconcerting.
