Don't you think that's more a matter of your attitude than whether these people are effectively worthless?
“It is the mark of an educated mind to be able to entertain a thought without accepting it.” doesn't seem to be fashionable nowadays but it's a valuable piece of wisdom.
Cancelling folks with this "lalalala I can't hear you!" attitude, against someone who offends a few sensibilities, is the problem here. People are imperfect, don't be so closed-minded.
