Simply passing that off as "bad wording" is reductive and gives leeway to others who test the waters with extremism and turtle back into the shell of "I didn't mean it that way" when they get pushback.
It's not that Garry literally means he wants them to die, it's that it's irresponsible for a leader to infer that idea and to normalize (unintentionally, as I would give him the benefit of the doubt here) the same type of actions as actual extremists.
