Edit: as for not returning to visit, I'm not exactly looking forward to being interrogated every time I try to enter, and possibly denied entry again, which I have read in many places will likely happen.
No. But if police officers are routinely rude to me, and if I see many reports of officers killing people and beating people - even people who pose no risk to those officers - then I might start thinking about where I live.
What is considered rude from a police officer in the US is when they shot you without warning (with a warning, it's normal).
They are lots of places I would love to visit in the US, but current policies are keeping me out (also: beard).
country X has political support for some sort of bad thing Y, therefore I will never visit country X.
They where "massive" by Swedish standards, but tiny by any international standard you may care to use. Certainly much much smaller than riots that have happened recently in many other European countries
so perhaps, my advice is, don't overreact.
As far as tourists and non-immigrant visas are concerned there is no debate and it's business as usual.
"The United States' share of the total travel market is down, to 11.2 percent in 2010 from 17.3 percent in 2000"
"There were also big declines in the same period in travel from France (down 23.2 percent), Brazil (down 20.3 percent), Germany (down 19.2 percent) and Japan (down 5.8 percent)."

I know I don't want to waste my vacation days playing bureaucratic Russian roulette when I could spend them in any one of the dozens countries that will happily let me visit with a minimum of fuss.
