As far as criticizing a president and call one a few choice words, ok, fine, whatever. But the death threats. Uh, no. Used to be when the secret service felt someone crossed the line one too many time with words, spoken or written, they'd show up at the person's door and warn them if there is a 'next time', the secret service will return with handcuffs and an arrest warrant for conspiracy to assassinate the president.
There was rarely ever a 'next time'.
Nowadays we got people putting up death threats toward whoever is the current president and it's gotten stupidly bad with Trump. It's time for the secret service to start showing up at people's doors and give the warning.
