If you try to convince them, likely you would get an unbelievable amount of negative online attention sent your way. Ironically the same thing they hate Kiwifarms for.
In practice: The abstract entity KiwiFarms takes all the shit, very few of the people actually constituting its membership seem to take much flak; meanwhile its critics look completely unhinged, even though they're absolutely right and KF is incredibly reprehensible, they still do their best to undermine the credibility of their own cause by acting and behaving like a frothing at the mouth lynch mob much more interested in power-tripping and revenge than truth and justice.
The strategy is straight out of Sun Tzu on how to deal with a stronger army, and I haven't really seen any examples of anyone handling it well.
