While the segment of the population who are motivated and able to engage with the public comment process may often not be representative demographically, it's hideous (besides semantically inaccurate) to dismiss them as a special interest group.

It also doesn't make sense to include negativity and positivity as part of representation. Yes, people feel more strongly about bad things than good things, but that's everybody. It would be a mistake to try to excise that. It's already our job to account for it.

From your tone, this seems less like an opinion on democratic process and more like you just happen to have the opposite opinions of most people in the aforementioned segment, statistically, and you (perhaps understandably) are angered by them, and you see a viable argument for reducing their voices.
