“TDS” is a prime example of a “thought terminating cliche” [1]. Certain people don’t have any real arguments of substance, so anytime someone criticizes their hero, they cry “TDS!!”, as if it someone discredits the other person’s argument. You’ll see similar stuff posted against criticisms of Elon Musk, where people will claim that it’s only because “he goes against the hive mind.”

It’s an incredibly lazy, unintelligible way of arguing, but alas…
