You're as free as any historian to form an opinion and share it. The rest of us can take the fact that you're not one into account while reading it.

Thank you for sharing a link to this series, I was not aware of it.

Imagine saying this about microbiology or something.

Dismissing people by saying things like "imagine joe six pack sharing his opinion on microbiology" is part of what made the anti-vax or vax-skeptical crowd so upset. In many circumstances, the rest of us did not meet them where they were. That requires listening, and yes, encouraging uninformed people to express their opinions.

It can be popular to behave dismissively online because it seems like you don't need to deal with the aftermath. When everyone does it, that adds up.

I'm not saying everyone needs to be out there correcting misinformation, just that we deal ourselves a better hand when we accept that other people get things wrong. It's okay for people to be wrong, even in the absence of being corrected. Telling people to shut up doesn't nip the virus in the bud, it is the virus.
