I think you are talking about
this post (different thread). In any case I agree that ultimately its about the what, not the how. If you think the police are heroes and the claims of justice-system-mistreatment are overblown, it doesn't matter how quiet (or how loud) the outcries/protests of the police are... you are going to find them irritating...
because you don't want to hear it, at all. Now of course the louder, more disruptive, etc., the protest is, the more its going to irritate you, but ultimately, it all irritates you...
unless you don't have to hear about it. So what opponents truly want is a "protest" that they don't have to hear about, and doesn't affect them in any way... and of course the best way to accomplish that is
not protesting at all.
But the problem with that, from the perspective of the aggrieved party, is that
you want to raise awareness of your cause for grievance. You
want their attention... so you are at cross purposes. They want to ignore you, and they want you to make it as easy for them to ignore you as possible. You on the other hand,
don't want to be ignored, and you want to make it as hard for them to ignore you as possible. That means, raising hell, disrupting their lives/status quo and making them uncomfortable,
with the means available to you... so say, for example... by electing a candidate they despise, and are deeply uncomfortable with. In that sense, this past election is a good example of a form of protest.
One important distinction, is that "
means available to you" part... protest-via-election is a tool that is only available to aggrieved groups that can achieve majority (or near majority) numbers... If you are not in that bracket, you have to find alternative ways to raise-all-holy-hell... but make no mistake, you must raise hell or you will be ignored... which is precisely why your opponents want your protest (or vote) to be quiet and orderly and respectful of the status quo... so they can ignore you.
