This is pretty much a textbook example of the unintentional but systematic racism that people of color face.
As to the studies and hard data, I’ve provided the best that I’ve found. You have so far provided only opinion and a statement (per the quote above) that institutional racism exists.
Maybe what I’ve been able to find isn’t perfect, but it’s better than anything else I’ve found, so I’m going with that until a better body of evidence is out there. I’m fine changing my mind if that’s what high-quality evidence supports. But I’m not going to be swayed by personal opinions and anecdotes.
It’s super easy to change my mind on a subject - show me better evidence of a contrary view and it’s done. I’d hope that everyone here would act similarly.
You see my intention was not to convince you and this thread is not about racism so I have little interest in spending a lot of time researching it.
But in my opinion, from what I have observed, experienced first hand, and heard and read, yes there is a residual racism that lingers in this country. There are people who do consider black people to to be <<insert whatever characterization here>> and that is almost always because that is what they have been taught and/or what they have experienced with black people.
Those who have worked and laughed and played and shared positive experiences with black people almost always have a much different attitude and that would be most of us.
But after you have hired a militant activist type with a chip on his/her shoulder and experienced how demoralizing such a person is to your other employees and what a problem it is to supervise such a person, it is human nature to not want to repeat that experience. Maybe you need some study or hard statistics to prove that. I understand it just using reason, logic, and one time providing experience. I wouldn't have needed the experience to understand it though.
My friends and colleagues close enough to have the discussion with me tell me that they have not been handicapped or disadvantaged professionally because they are black. But they come to hate the perception that because they are black they can't be treated like everybody else. They have to be a 'credit to their race' or 'sensitive to stereotypes' or are asked to 'express the point of view from a black person's perspective'. They are aware that when they are present, people struggle to find ways to word things or make a point that won't offend or be interpreted as racist. And there is always the underlying perception that they got their educations and positions or were promoted because of Affirmative Action or to fill some quota or whatever. In their opinion, it is that kind of thing plus the race baiters who use racism for political or financial advantage that bothers them the most. They get really tired of having to think, speak, behave, i.e. be what others demand that black people be.
Now fast forward to the thread topic and the TDS crowd. They hate President Trump first and foremost because he wasn't supposed to win. It was Hillary's turn. But also he doesn't speak as they demand he speak, he doesn't react to things they way they demand he react, he is politically incorrect, he doesn't do things the way they have always been done, he steps way out of the box to find solutions for problems, and he is willing to break a few eggs to make a good omelet which most President won't do. He is required to be what THEY say he should be in order for him to be acceptable.
Pretty much the same kind of thing.
