An overused tactic?

I would like to think the comment below was correct but I do think that it is only partly so. The accusation still has some power to embarrass less cynical people

"It has come to the point where the term ‘racist’ has become so completely overused that it is losing its impact. There was a time when a person so accused would take great offense and spend much time demonstrating a lack of racist tendencies.

The typical response now is to sigh and accuse the other person of making the accusation due to having run out of actual arguments. The reason it was overused is because the person making the accusation typically did resort to it due to having run out of actual arguments.

Now an outside observer, hearing a progressive refer to someone else as a racist, hears ‘he’s saying that guy isn’t a progressive.’”
