A random tweet isn't context! Not everyone is drinking from the shit pipeline that is Twitter. All I got from that Tweet was some guy isn't another guy?
Provide some co text like a news article or something. If you can't provide some context for people to understand maybe that's the signal to you that whatever random shit you're talking about doesn't quite rise to the level of seriousness of the President spewing unsubstantiated bullshit as claims of fact.
If you think some "leftist" was making absurd claims of fact or saying demonstrably untrue things, report them to Twitter asking for their post to be flagged.
