(The piece where the author suggests focusing on "technical arguments" when the issue at hand is fundamentally political is frankly laughable; can't really tell if it is naïveté or deception.)
It is essentially just asking for constructive feedback. When people just say not to do it, insult the author, or make assumptions about the proposal that aren't true the comments are not actionable.
Even if an issue is political you can still make a constructive argument on the risks that adopting the proposal has.
You know, if your government body of choice came up with a terrible idea in a draft bill and enraged the population, it would not be appropriate for them to go on TV and say “the population should offer constructive criticism in the form of legal arguments”. So what the fuck is this guy saying exactly, that you feel is a valid approach to handling public outcry?
