Trump will be gone in two to six years. He isn't a ruler, he was democratically elected President. There is no scenario where he remains, Trump is not a dictator or ruler just like George W. Bush (accused by the left) and Obama (accused by the right) were not.
Further, Trump wasn't elected by a fake extreme majority as with Putin, he squeaked by courtesy of the electoral college system. His opposition spent three times as much money as he did and had nearly all of the media on their side. He is popularly and very openly opposed by nearly all elites in the US, all media, all talkshow hosts, the large majority of pundits, all celebrities and nearly all large media companies. Trump is not placing his opposition into prison or silencing them (even if he wishes he could, he can't), see: Schumer, Pelosi, Harris, Feinstein, Clinton, Booker, Bezos, Soros, Reid Hoffman, Tom Steyer, and a thousand other prominent examples. Snoop pretended to kill Trump in a music video, try something equivalent to that in China or Russia, see how long you last. Every celebrity in Hollywood routinely attacks Trump and his policies, often viciously, with zero legal consequence. In China they disappear prominent people for a tiny fraction of that behavior.
Can you imagine what would happen to a prominent musician in China that made the first lady of China (Peng Liyuan) a stripper in a music video, as recently was the case with Melania? Most likely they'd never be heard from again. What did Trump do about it? Nothing, T.I. will continue on expressing his views and art.
The First Amendment is clearly very much alive and well in the US.
There is a mountain of anti-Trump sentiment and protest across the US and has been for two years now. It is not being silenced or stopped, it's on nearly every TV channel 24/7 and it's all over the US Internet.
Now please contrast that with Xi and Putin vs their opposition, domestic protest, what you're allowed to do in opposition in China and Russia, and so on.
