Not sure if anyone can feel anyone else's pain. If millions of people are complaining about a problem, why try to say the problem does not exist?
My experiences are nothing compared to the terrible stories I've heard from PoC, but I'll give you an example. I'm Muslim. In 2004, I ended up on the restricted fly list, effectively ending my Management Consulting career. My co-workers kept telling me, "just take your shoes off, get thru security, and stop complaining". None bothered to hear my real issue -- i could not fly. Forget security, I could not get a boarding pass issued. It would happen randomly, about 50% of the time. Once, I was stuck in Europe, unable to get back home (FYI: as a US born Citizen.) Many times, i'd get half a boarding pass and be stuck at some random airport (ATL, ORD, etc.) Once I had to take a train back from Washington DC because I couldnt get on a flight.
Co-worker opinion mattered, because it affected my ability to get on local projects (where I could avoid flights.) Eventually, I had to leave the consulting firm despite an imminent promotion.
It is so easy to dismiss people, but seriously -- if millions are complaining -- just accept there is probably something there.
Millions of people complaining about "Muslim terrorism" led to you being inappropriately placed on a no-fly list. Millions of people complaining about "the Jew" led to significant and severe atrocities (plural...).
Millions voted for Trump. Millions voted for Clinton. Millions voted for Bernie. And millions will vote for the next Stalin, Hitler, or Mao.
I don't disagree that there is a problem with policing but I can't conceive of a more evil world where millions of people are just listened to without question.
