"Violence" is an emotion word and when used by a leftist, has no definitional content at all. When your ideological presentation is devoid of facts and reason you have only emotion and anyone who does not support the slogan or leader of the moment is Enemy and all words that have emotion arousing character are employed. Very quickly mild word. become useless and ever perceived stronger words are deployed. It doesn't matter that the adjectives and epithets used are wholly inappropriate to the situation because the words, again, have no definition. If you are an Enemy then every word that conjures up feelings of danger and hatred and disgust are apply to you. They all mean precisely the same thing, that is, You are the Enemy.
It is therefore a waste of time and energy, it is pure futility to argue anything at all with a liberal of any self designation.
