The definition is specifically crafted to make any claims of racism against white people nonsensical.

Pretty much my whole point.

Because it relies on the claim that white people hold institutional power

Semantics used to disguise the fact that it is a shaming term targeting at a single, specific race.

though not all white people in equal degree, as you seem to overlook.

This is nonsensical for a couple of reasons. 1) That's completely ignoring all the leftists, blacks, jews, etc that constantly shriek All White People Are Racist!" 2) Its like saying "Not all black people are niggers." When every black in America knows very well that YES, they are a nigger. Its simply another attempt at hiding the true meaning of the word.

Any white person is going to be socialized into an atmosphere and ideology of racism in America, its simply the way they are raised.

All humans have a natural and instinctual in-group/out-group bias. If anything, White Americans are socialized more than any other People in the world (except maybe Western Europeans) to suppress this natural survival trait. Your pet word is a major factor in this.

Racism is a way of highlighting and shaming white people who exercise their power against minorities, because minorities obviously lead better lives when they aren't oppressed.

Racism is a term meant to shame White People into suppressing their natural HUMAN instincts, and allowing Outsiders to exploit them and their resources. Same thing you said, just a little more honest language.

I believe that all humans deserve certain rights, like food, shelter, and other basic necessities. These ought to be provided by the community, coming from their common labor.

I believe that communists should be thrown from helicopters, or shot in the head and dropped into a mass grave. Everyone has opinions.

Given that racism is about exercising white racial power against other races and removing these basic necessities, it is against my moral views and ought to be against any person who values the quality of life of other human beings.

When you say "White Racial Power" what you really mean is White Superiority in various areas such as IQ, Technological Development, Resource Exploitation, Warfare, etc. What you are saying is that White People are so much better in these areas than non-whites, that we should be ashamed into handicapping ourselves and giving away resources to those very groups that hate, shame, and insult us.

TL;DR - "Racist" is nothing more than an anti-white slur, no different than "Cracker" or Honkey".

And your "moral views" are garbage.
