ISIS is successfully organizing and recruiting using these channels. Is there any indication at all that these channels allowed dissenting voices to reach ISIS supporters? That these voices had any impact on them at all? That if they had any impact, it was large enough to be a worthwhile tradeoff?<p>This idea that just by talking to someone no matter their opinion or how extreme they are in pursuing it, you can convince them to be wrong, may be attractive but it&#x27;s questionable at best. American politics, conspiracy theorists, antisemites, nazis there is absolutely no shortage of people with extreme opinions that are confronted with dissenting voices. You will find it challenging to find these voices having any positive impact at all though.
