Even the next part:

world’s richest man does a Nazi salute at a political rally,

Don't get me wrong, horrible and completely unacceptable.

But sure as shit is nowhere near the line of what's happened with the last 100 years:

The Business Plot, also called the Wall Street Putsch[1] and the White House Putsch, was a political conspiracy in 1933 in the United States to overthrow the government of President Franklin D. Roosevelt and install Smedley Butler as dictator.[2][3] Butler, a retired Marine Corps major general, testified under oath that wealthy businessmen were plotting to create a fascist veterans' organization with him as its leader and use it in a coup d'état to overthrow Roosevelt. In 1934, Butler testified under oath before the United States House of Representatives Special Committee on Un-American Activities (the "McCormack–Dickstein Committee") on these revelations.[4] Although no one was prosecuted, the congressional committee final report said, "there is no question that these attempts were discussed, were planned, and might have been placed in execution when and if the financial backers deemed it expedient."

In case anyone's eyes glazed over instead of reading, two key points:

wealthy businessmen were plotting to create a fascist veterans' organization with him as its leader and use it in a coup d'état to overthrow Roosevelt.

And even more importantly:

Although no one was prosecuted, the congressional committee final report said, "there is no question that these attempts were discussed, were planned, and might have been placed in execution when and if the financial backers deemed it expedient."

Shit didn't just get bad, it's been bad.

And the way to fight it is an opposition party like FDR.
