THE SJWs use the simple trick that if you even question their assertions, then that automatically means that you are a racist or a Nazi. It’s not “brilliant.” It is simply a matter of name-calling to shut down any criticism of their lame arguments. They use intimidation, shaming, smearing, and threats of violence to censor their opposition, and they continue to get away with it ONLY because they have a sympathetic press and sympathetic professors and college administrators. If a conservative tried to use these tactics, they would be severely castigated by the press and the academy.
You just have to call them out on their own hypocritical views. When having to deal with people who hate Thanksgiving or Columbus because of the treatment of the Indians, taking their land and violating treaties, I always point out that they're the biggest supporters of socialism, and therefore have no problem with taking the property of one and giving it to the other, and think the Constitution is a living, breathing document meant to be reinterpreted from time to time.
It doesn’t have to be brilliant, it just has to be effective enough to shut down any opposition until the communists can take over society.
