I struggle to understand what the point of this comment is.

Yes, we know, opinions are like assholes, everyone has one. You don't have to believe him or agree with anything he says. That's ... how it works.

I generally find his posts quite helpful and useful. Even ones where I might not agree with him.

Your comment is noise. It's just blind criticism without actually saying anything. I don't find it helpful or useful. "His value system could be valid or not valid". Also, water is wet and British food sucks.
