What consequences should Gary face?
So, in the end, it can be everything from nothing to a criminal charge and conviction with loosing his job somewhere in the middle.
Even if you take "die slow motherfucker" literally, it's not a threat. A wish that someone dies is not a threat. "I will kill you" is a threat.
People talk shit all the time, a lot of people in this post need to calm down and stop being so quick to be offended.
Should have said it? Probably not. Does that make him a danger to anyone? Not by itself it doesn't.
Saying "die motherfucker" makes it less obvious. Since the other extreme of "this person should die" is crude, but not a threat (lest Twitter would be shut down overnight). So it'd come down to the judge and how they interpret the phrase to get any headway

And that isn't right as a concept. "Shit talking" is almost never necessary in modern discourse. But the US has strong libel laws so "talking shit" won't lead to much legal consequence.

It isn't polite speech that needs to be protected and the tests for whether something is an actual threat or not is well understood, there's no excuse for you not knowing them unless you don't live in the US.
I'm not a lawyer but I'm just saying that I can see it being argued based on the phrasing and how far the subjects wanted to escalate this. Whether or not it would be effective or viable is another question.
One of the reasons for this precedent is to prevent exactly what you're attempting to do here, which is to curb someone's freedom of expression using the law.
