I'd be more on board with these protests if they were directed at a state visit from the US generally and not just at the current president who happens to be a very unpleasant person.
The foreign policy of the USA and the west is inherently racist. Black & brown people are literally expendable in the pursuit of hegemony and profit. Madeleine Albright and her book have been pimped around the media recently, despite her saying the death of half a million Iraqi kids was worth it. Who on earth could think that's reasonable? The media is incredibly powerful when it comes to deciding who is and isn't acceptable.
I'm personally more triggered by the invasion & destruction of entire countries and the drone bombing of wedding parties than by the behaviour of a TV celebrity whose election into office is only a symptom of a seriously fucked up society and political system. Trump is awful but temporary, and the media circus around him is 90% ratings and 10% virtue signalling. There are a lot of worse things going on, which have been for a long time.
