No - I don't think that's the case. I think for all people they're uninformed on almost everything, because there's just too much stuff to be informed on. They probably should either fence sit or be careful about holding opinions that are too strong. I wasn't even fence sitting, just pointing out there's hypocrisy on all ends of the political spectrum - including the fence sitters.
I think people who think that complicated issues are simple and there's one easy answer are wrong and those who do are either or both holier than thou virtue signallers or not nearly as smart as they think wannabe intellectuals.
My buying advice for cars 'i have no idea, it depends I suppose' - because, well, I have no idea. My buying advice for cook books will be pretty opinionated (probably not right though). I don't see that taking a side (especially strongly) when I'm un or under informed is a virtue.
