actually, blacks commit violent crime at a very high rate compared to their population. so they are "more dangerous". also I think you overestimate the population of people who are actually racist in this country. the new online media outlets (Ex. vox, buzzfeed, gq) all try to shock people into thinking there is a white nationalist uprising going on in our country right now. but, if you look at their reporting on Charlottesville, for example, they labeled the large crowds of men with torches as Neo Nazis, when in reality the vast majority of them were just everyday people who wanted to rally for right leaning views and the preservation of our history including the monuments. also, about racism being ingrained in our society and institutions, it is well known that our universities very often lean far left, and they are definitely not making new adults into racists. society absorbs all forms of media, news included, which is mostly liberal. therefore, the notion that black people are more dangerous isn't ingrained in us. this is just an unspoken fact. and sure, I may get nervous when I see a group of black people, but this is all about time and location. for example, walking past a shady looking group of people on the sidewalk late at night, the first thing you are going to think is "am I in danger?". you're not going to care what color they are because it doesn't matter. any group of people regardless of skin color could potentially be dangerous.
