I found a book in the library inventory that looks like it's especially needed by flat-earthers and other such conspiracy theorists!
All snark aside, the Dummies series is becoming a really handy how-to source for almost anything. It has expanded far beyond just computer program guides, so there's probably a book for a hobby you enjoy or a topic you want to study. Check the catalog at your local library! And if you find the series title insulting, there are plenty of other books on even more topics there, too.
Careful with giving that to flat-earthers lest they say the Dummies series is also a tool to spread the "conspiracy" (word they LOVE to throw around indeed) and call you a sheeple, which is so ironic considering they love to jump in the conspiracy bandwagon hahahaha
IT'S ALL CONNECTED!
