Because I've conceded that the ones I discuss don't represent the entire movement. I've conceded that the movement has caused problems, serious problems of crime and sanitation. I'm just asking for reciprocity.
Posting over and over anecdotes of problems without context, without a discussion of what those problems means doesn't leave much room to imagine the purpose. Anecdotes without context or discussion strike me as blatantly ad hominem. To discredit the movement on the basis of some percentage of the people there.
Do you really need a disclaimer with every post that clarifies that the actions of some do not always represent the group?
