Onomatophobia is a fear of certain words sometimes because of a bad experience associated with that word.
Oddly, the left may think the riotous troubles at the Capitol were all too fearful, and thereby they refuse to hear the word fraud for fear of further provocation.
This doesn’t hold much water because, conservatives should have far more fear after what happened at the polls – but they are not afraid of the word fraud. Injustice is the feared word among conservatives.
