I understand the anti troll empowerment side of the argument.  My 2 cents... an ignore button, stops or filters information, both good and bad.  Successful conveyance (viz. encryption keys or the telephone) usually requires a duplex mode of communication as knowledge is not imparted by osmosis and not even the best teachers in the world are mind readers. Pressing the ignore button, like hanging up, defeats that duplex mode.

I know little, and what I do not know is immense. Those who think they know everything, prove they know nothing. Even the village idiot has a voice. Practitioners of conscious ignorance click the ignore button, because that's what an ignoramus would be expected to do.  Their blissful ignorance is their own choice and no one else's.  

IMHO society as a whole has a huge problem with those who choose to be ignorant despite the best efforts of others. All one need do to exemplify this is look at the political rhetoric du jour, and the rise of populism.  Ignoring a problem does not make it go away.  Martin Niemoller attests to that fact. 

At the end of the day… resisting your natural way of being can be unhealthy, and as there is no pill for ignorance either, choosing to click the ignore button would seem to be apropos in perpetuating self induced or conscious ignorance.  On that note, we shall leave the ignorant, where they are and wish to remain… Out.
