The actions of a minority of individuals in a movement do not define what the larger movement is. A movement is also not defined by the people who seek to misrepresent the movement to others. The actions of the majority of the people in the movement are what defines it. Arguments directed at individuals, especially those individuals that do not represent the larger movement, neither change what the movement is nor are they compelling.
I personally recommend the hierarchy of disagreement. Arguments that focus on the refutation of arguments will be more compelling than those directed at the people giving the arguments.
