I 100% know that everyone, myself included, obviously holds about 0.0001% , give or take a few orders of magnitude, of the actual knowledge that exists in the universe.

And yet everyone, myself included, holds opinions on things that lie outside this sphere of known individual knowledge. The vast majority of people have far greater scopes of opinion on things that they don't really know than the scope if things they do. And most of this opinion is regurgitated bullshit from the media.

Unless you're a semi-omniscient superhero aid from a bad comic book, the same applies to you.
