You mean falsely yell 'fire' in a crowded theatre - an exceedingly important distinction which is core to much discussion about free speech (should offensive speech be allowed if it is stating facts etc.)
I wasn't suggesting otherwise. I was comparing the amplification of social media with the concept of yelling in a theater.
You mean falsely, otherwise your 'clear and present danger' part doesn't make sense - the entire point historically with your example is that it is perfectly acceptable to yell in the theatre if there is clear and present danger. Reducing it to simply 'yelling in a theatre' means you're evaluating it just on.. yelling alone? What? Are you saying all 'social media amplification' is the same?
The danger in 'clear and present danger' of yelling in the crowded theater is specifically and intentionally causing panic where people are likely to get hurt. As others have mentioned, though, it's complicated. The original poster was suggesting we need new laws targeting the amplification of social media, which could limit false and damaging speech. My suggestion is that existing speech, slander, and libel laws apply. The 'amplification' of social media gives individual voices more reach and clout, similar to yelling. Social etiquette, law enforcement, and the judicial system have yet to adapt.
Is it knowingly falsely yell fire? Or just falsely yell fire?
