I don't think a lot of upset Americans realize that threatening the president of the United States [on social media] is a Class E felony (2-5 years). FYI: this has always been the case - for Clinton, Bush, Obama, and now for Trump. Thought you should know, especially because there is a long history of it being enforced. Oh, and no, death threats aren’t constitutionally protected under the First Amendment.
Wikipedia detail: “ Threatening the President of the United States is a class E felony under United States Code Title 18, Section 871.[45][46] The offense is punishable by up to 5 years in prison,[45] a $250,000 maximum fine,[47] a $100 special assessment,[48] and 3 years of supervised release.[49] ”
Insult Trump all you want, but don’t threaten him with violence on social media.
