Don't Give Scott Adams This Much Credit (Are You Kidding?)
Scott Adams is one of a large number of sociopaths in media who live to see chaos and anarchism, so use their influence to rally various factions to start tearing each other part. They have been part of media for decades now. This is what they live for, to see the country in civil war.
The point is that calling him a racist would be giving him too much credit. He is trying to start a war in this country, like all the other sociopaths like him who've made a career out of starting shit with various groups (Howard Stern, Bill Maher, Ann Coulter). Some people just want to see the world burn. He is one of them.
