Your reasoning assumes people don't skip steps in the process of learning things. There are cliches to support my case. "Only knows enough to be dangerous" "More dollars than sense"

That itself is dangerous. You're basically discouraging someone from offering advice to the general public because you think the knowledge is generally known, but that's just not the case.

I have a general idea of what I'm doing but reading that comment changed my perspective of what is and isn't dangerous in a car and those dangers shift from ICE to electric.

Frankly, I'm glad he opened my mind to the ideas.
