Another observation on 'Never Again'...

...do you ever notice that when people write stories on the Holocaust or anti-Semitic violence, such as this one, they always talk about how people say "We must never forget that this happened!"...but they never really offer anything on how to actually prevent it from happening again? Beyond the empty rhetoric of "increased understanding and tolerance," that is? I know armed resistance seems to be so un-PC, but ultimately that's the only thing that'll stop some people. You know, sort of like it did the guy who took the rifle to the Holocaust Museum the other day. There are just some people whom the appeals for "understanding" and "tolerance" just won't reach...but no one ever mentions what to do in instances like that. It boggles the mind, it truly does...
