Luckily most of the people here, if they wanted, could easily get an entry-level education in any field, because they know how to study from books, can get access to the material, etc.
You can only have democracy if everyone has the chance to educate themselves on the topics that are relevant to them.
If, in your country, the majority never learnt how to do so, then democracy will inevitably fail. Many people in STEM or other sciences have an advantage due to that, but this should be standard for all.
I am saying, the people here could actually make qualified comments, if they wanted to. They could learn about the topics they comment on.
But they choose not to.
Which is a different story from most of humanity, which doesn’t even have a choice, doesn’t have a chance to learn.
