It is still used in the west today to shut down non-conformists. Think about it, why aren't Jews ever considered "racist"?
Trotsky aka (((Bronstein))) was a Marxist Jew who used this term to justify the destruction of European peoples and weaken their self-protective instincts and identity as a tribe. It is applied ONLY to Europeans. It is used as a method of control when any European dares to see anything from his own point of view or try to protect himself and his people.

So you are going to hear this:
People can't change the physical characteristics of their birth. To judge someone purely by a physical characteristic is wrong. They should be judged by what they do.
The problem is you can't judge the cultural behaviors many people with that characteristic share and you can't judge what they do because of that characteristic.
Are you familiar with the concept of heuristics? A heuristic is essentially a shortcut to solving a problem. The inverse would be an algorithm. Here's a very brief example:
If you're trying to call your friend, and you can't remember his number, an algorithm to solve that problem would be to dial every seven-digit combination of numbers until you found the right one (starting at 111-1111 and ending at 999-9999). But if you happen to remember a few seven-digit phone number combinations and you just can't recall which phone number belongs to which friend, a heuristic to solving the problem would be to dial each of those phone numbers until you reached your friend.
The human mind is programmed to rely on heuristics in everyday life. It's why we naturally categorize things. Without heuristics, we would be incapable of getting anything done. But the drawback of heuristics is that they're not always as accurate as algorithms. Algorithms are guaranteed to work 100% of the time, but they're exceedingly time-consuming. Heuristics have a moderately high success rate, but they save you a ton of time.
Racism is a heuristic. Ideally, we would judge every single person we encountered in our lives by their history, their personality, their past actions, and their behavior. That would be an algorithm. But that's quite literally impossible. We don't have time to do that. So instead, we rely on heuristics, i.e. "every little old Chinese woman I've ever met has been friendly and non-threatening, so when I encounter a little old Chinese woman, I feel safe." But we all know based on crime statistics, and many of us know based on personal experience, that blacks, both male and female, have a greater-than-average chance of being aggressive, unpredictable, and violent. So understandably many people prefer to avoid blacks. There is nothing wrong with this. If we had time to personally vet every specific black person we encountered, racism would be cruel. But we don't.
The proliferation of the idea of racism in Western society was thanks to the Jewish infiltration of the humanities and social sciences. Upon entering academia, a large contingent of Jews worked tirelessly to eliminate the idea of race from anthropology and normalize the idea that all races are the same. To substitute race, they pushed baseless theories (literally baseless; all of their studies have been discredited repeatedly by biologists and social scientists alike) that attributed differences between races to culture, and summarily dismissed the idea that culture could be a product of race.
Furthermore, they explicitly did this in the furtherance of Jewish interests. They felt that if the goyim were conscious of race and had no qualms about associating certain attributes with specific races, then the Jews would be at risk of being singled out as a distinct group and the (((holocaust))) might happen again. Here's a brief summary of everything I've just written. It's a very easy, quick watch -- under 10 minutes. I encourage everyone in this thread to spend that tiny amount of time learning something new today.
