I thought about this for a while, and I think a core issue is that it demonstrates an inability to grapple with the subjectivity inherent in discussing game design-- its an art form, there isn't firm ground to fall back on to differentiate the normative statements being made by me or in opposition to me, the framework through which we might draw a distinction between the desires of the individual and what is/isn't "actually" faulty is self-referential. Any statement made on what might constitute good design is intrinsically subjective, and this could apply as a criticism of it.
We fundamentally don't do that with anything else artistic, its certainly possible and acceptable for someone to set themselves in opposition to my ideas-- but the underlying notion that my framework is any different than say, an edwards essay about what makes for good design, a class on what makes for good writing, a Justin Alexander blog post about how you should prep situations rather than plots, the assessment of an experienced judge in a cooking competition, isn't super defensible.
That's why I think this is problematic, its policing the same thing everyone else in this thread is doing, including the people trying to make it a problem, and they certainly aren't obsequious about their views-- the tone is consistently just shy of caustic.
