Don't make up lies about a dead man's claims from over a decade ago. Pretty basic rule. Unless you're writing clickbait, then by all means do whatever the hell

Don't make up lies about a dead man's claims from over a decade ago. Pretty basic rule. Unless you're writing clickbait, then by all means do whatever the hell you want. If you're going to call someone a liar, test their claim. Don't go "they were lying, because a decade after their death everything is different".
