Sure it does. No true scotsman breaks down to a claim that some group has some Trait, then claiming that because some individual does not share the Trait they are by definition out of the group. I guess sometimes it's valid, but not here. Anon hasn't shown itself capable of an attack like this and if you look at the attacks by anon on scientology you'll be left wondering they were able to form a group identitiy with their fringe (core?) As it is.
Palish might be right that this doesn't sound like its from any of the main group.
