Very different from security through obscurity. The problem here is that a vocal minority can sway opinions and make it seem like lots of people are behind something. One lengthy disagreeing rant might seem like a one off. Ten lengthy rants will likely cause a moderator to pause and listen and maybe even respond.
In the end, the mods will need to decide how to handle shit and while input from mere mortals is a good thing, it is not required for them to do their jobs. We already have very democratic tools here and lots of power: more so than inmost other societies. If you really disagree with something, by all means speak up. But mods are not elected officials representing your interests. They are not here to enact the will of the people. They are here to maintain civility and ensure that the rules are followed.
