I decided a long time ago that I will never travel to the US because I'm not white and cares about my privacy.
That's an absurd decision. The US has tens of millions of annual visitors, and given that the majority of the Earth isn't white, it's likely that a majority of the visitors aren't. While the stories that hit the press are negative (and hence newsworthy), millions travel in and out without incident. If you look at this statistically, you have a one in a million chance of having your phone searched at the border
The fact you have no human rights within the boder and must follow every orders from police without requiring the court order or face violence, detention without arrest, declined to contact the lawyer, or simply be shot are enough to avoid such place.
