It’s that “when appropriate” which is key, along with “in an appropriate manner.” I absolutely support resisting these thugs (& this “administration” in general), but I fear in the heat of anger it’s all too easy to dehumanize them, which makes our side no better than theirs. Often they even deliberately try to provoke such a response so they are “legally justified” in going over the top in “defending themselves.” It’s a tedious & difficult game to come out ahead on. I feel it helps one restrain emotions and keep from reacting to their provocations if one always tries to keep in mind that their opponent is just as human as we are. Be resolute in resistance, but not violent unless you have absolutely no other choice.
