I think the term "racism" has been softened and blurred to mean something it's not. For example, it's not racist to not want to date outside your own race. It's not racist to discriminate based on race if there are reasons that don't include the notion that one race is inherently better than another, even if the notion is ill founded. For example, some ins utions actively look for black students, and they may turn away a white or Asian student just as academically qualified. That's race based discrimination, but it's not a racist policy as it seeks to correct social imbalances brought about by centuries of treating other humans like property. I see the term being use to define people who get offended at being called privileged, when they are dirt poor, just because they are white. Being offended by the concept doesn't make you a racist, it doesn't mean you think your race is better than another race.
Other than the neo-nazis and actually some minority cultures, I don't know if true racism even exists any more. I know racial profiling exists, and stereotyping exists, and unfair legal practices and ty upbringing exists, and that people are slaves to their experiences. You can say some of that is a "form" of racism, but when true Hitler level racism gets conflated with basic cultural ignorance, that's where conversation stops. Labeling everyone who disagrees with your take or refuses to take a knee during the anthem as a "racist" is wrong. It seems extremely popular though as an instant win button.
