That very article proves to me that we have cause for concern. Forget the article and look at it from where I'm sitting. If you go to Google Images, search for "Dachau" and find a pile of emaciated dead and dying bodies, you may as well be looking at my family's photo album. My great-grandpa will be in there somewhere. Why? Because we gave Nazi scum their precious freedom of speech before.
Yes, I believe in freedom of expression. I don't believe we should censor the "N" word from Huck Finn anymore than we should translate "The Jew Among the Brambles" (Grimm's Fairytales) into "The Miser in the Bushes." I will soon have watched every episode of South Park, and I can't get enough. But there are some things you just don't do. One of them is promoting the supremacy of one race or the inferiority of another. This is basic stuff.
But that's not the focus of the article. It's not on how hate speech begets organized discrimination and ultimately violence. The focus was on the "militant" Jews and their boycott. But no matter how you spin it, the boycott isn't even unreasonable. Is anybody going to boycott them because their chicken soup isn't registered kosher? Is this an inverse Kristallnacht? Well, no. The closest I can get to giving you my family's oral history of the Nazi takeover is with this video. It's worth eighteen minutes of your life.
