Thank you for your thoughtful answer, Rachel.
Thanks for offering to do that, but I wonder if you realize how much work would be involved. I've done it with a few of the neo-Nazis, and it's not a question of blindly reverting. You have to rewrite their edits, because their writing is often poor; you have to resource their claims because the sources are often white-supremacist or personal websites; you have to answer their questions on talk and stay civil and respectful; you have to steer them in the direction of policy, and explain it to them many, many times.
Thanks for the warning. Yes, I think I do realize that. I tried rewriting the [[Eustace Mullins]] article after the User:Amalekite edit skirmish and I haven't been reverted yet. Hopefully that's a good sign.
It's not easy to do this all the while knowing that the editor (in this case) personally believes that his Jewish Wikipedian colleagues are sub-human.
I can only hope it's good exercise for the spirit.
Amalekite represents a tiny minority of nutcases who believe that certain ethnic groups and races are not fully human and do not deserve to live.
I believe this is a minority view, even within the racist movement. Other parts of the racism spectrum are, I fear, rather more common. Common enough to form a significant minority view in some cases. Exactly where on the spectrum User:Amalekite dwells I do not know but he did not seem to be pushing the idea that certain ethnic groups do not deserve to live.
I petition you: Lift your ban on the user. If he returns to editing (which I think is fairly unlikely) I'll undertake to babysit him and if he breaks any rules I'll immediately take the appropriate action.
