Wondering what effect if any some of the more extreme red flag laws might have on social medias. Just thinking, if the idea is to investigate and possibly arrest someone for rants they might put online would that make social media a more polite society?

Spicy political talk that doesn't tow the establishment line will now be termed a "manifesto," and be deemed justification for Red Flag actions against their authors. Once they've proven they're not a future mass murderer, they can have their guns back. As for their dogs, they will not be restored to life. Them's just the breaks.

or don't go/post on social media...??

Social media causes more harm than firearms.
