The term "racism" will be obsolete when enough whites no longer cower by the use of it against them. When they realize it's a leftist-created tool used to shut them up and out of any rational argument regarding race, ethnicity, and why such factors can actually be important to civilized society and Western ideals.
The proper response to being called "a racist" is NOT "I'm not a racist!".
That's SURRENDER from the moment you cry it.
Instead, the response should be "I don't care what leftist words you use, I'm still going to believe what I believe, think what I think, and say what I say…"
