You are so right. Among 325 million people, there is nothing imaginable that some "some people" are not. But I can remember whites and coloreds signs and when just having someone of another race to dinner made you a left-wing progressive. I find it bizarre to hear supposedly educated people claim that things are worse than ever. And it's not just race--it's sexism, gay/trans rights, rights of the disabled, rights of the elderly... In my lifetime, almost everything in society has mobilized powerfully against those "some people." The only area that has not, and arguably has moved backwards, is incarceration and its aftermath.
