<p>There’s a big difference between making a choice not to support things you don’t agree with and saying “x should be stopped; it should be instantly stopped”, which implies at least that there is or ought to be some agency that has both the authority and the effective power to stop it.</p>
<p>Again, we’re not talking about genocide, which SHOULD be instantly stopped (although in any particular case it can get very complicated to figure out who should spend the money and risk the lives it takes to instantly stop it, and no known nation has a great track record of stepping up to the plate for that). We’re talking about making jokes about genocide, a premise of which is that genocide is a horrible, bad thing (but apparently not so horrible and bad that one can’t make light of it).</p>
