It is absurd to expect any one person to have expert or even basic knowledge about every possible topic, in societies as complex and multi-faceted as ours, and it's just as absurd to expect people to have that knowledge in whatever topic happens to be *your* specialty.

In other words: complaining about how "everyone should know the basics of X" or "people are too dumb to understand X" is being an asshole and gatekeeping at best, and most likely you're also being ableist. Cut it out. I don't care what the subject is.

Like, work on making things more accessible and approachable instead?
