Have you considered that, rather that having some kind of sinister intent, other people simply have a different opinion on whether a particular idea is new or just a reworking, whether a previous idea is applicable to a current context, etc, etc?

To go way back up to your original post I kind of agree with you on subjectivity but I really don't see how you're then arguing that your framework demonstrates that Rawls etc have been 'debunked'.
