I mean, people could at least give us some plausible hypothetical action Trump could do to win over all of us who deeply loathe having him as president and want him out of office as soon as possible. Unless he stops in his tracks this minute and begins working overtime to make amends for all the racism, xenophobia, homophobia, and all other forms of hate him and his political career has unleashed, I'm not interested.
The reason people are attacking Trump for shoving the PM of Montenegro is because it fits his attitude towards our allies. Donald Trump has a history of incredibly rude, boorish, aggressive behavior towards our allies. This isn't some "eatin crackers" moment where people are hating on him just because haters gotta hate, but rather because he's established a pattern of behavior that makes us dread any opportunity Trump has to interact with American allies. He's destructive.
