We should stop talking so much about it in the first place, to quote Morgan Freeman. That is what underpins racism. In the West, racism has practically disappeared over the past 50 or 60 years, and the only people who still promote it are progressive talking heads. They are the real racists, along with those who repeat themselves. Another area you can focus on is fans of sporting events. If some of them shout racial epithets or make fun of minority athletes based on their race rather than their performance or behavior, give 30 or 40 of them a black mark at every game and prohibit them from entering the stadium again. Avoid correcting too much, but create terror in the audience to think twice about their actions and watch their mouths.
