why are you amazed and dismayed at people reacting to a threat?
why aren't you amazed and dismayed at the loser douchebag making the threat?
who needs to threaten people except a malicious person or a stupid and violent person?
most of it is empty, yes, until one asshole delivers. so you have to take it seriously as no one socially normal or well-intentioned makes violent threats
it is MEANT to cause fear
that's the actual problem genius!
that's how freedom is curtailed: by making you question your safety where you should feel secure
