The tweets exist on "both sides." Sure. But how effective and endemic are these misleading tweets in each sphere?

I'm having a real hard time thinking of analogous lies on the left that have readily observable support or momentum in comparison to misinformation like the origin, religion, or race of a mass murder and/or claiming that an elected president wasn't actually born in the U.S.

Hard to dismiss such misinformation that's heartily consumed and propagated in whatever sphere as just being "tweets" or saying "it exists over there too!" when the effects of said misinformation in each sphere are significantly different.
