On the long slog through Exodus, this jumped out:
You must not pass along false rumors.
Exodus 23:1 (NLT)
That would probably cut the fake Russian news and the out-of-context viral videos and the conspiracy theories of whichever side down to manageable proportions.
Not clear on whether this implies that it’s OK to go ahead and pass along true rumors.
“When in doubt, don’t,” maybe?
