It shows the ACLU is self consistent, which I find a good thing ever since they stood up for the right of the Nazis to hold a march in Skokie, Illinois (a then heavily Jewish community with a substantial proportion of Holocaust survivors).  I can't say I have the same regard for the highly respected (in many circles) Southern Poverty Law Center in especially the last ten years.  This, coming from a member of Jews for the Preservation of Firearms Ownership.  (And again, no, you don't have to be Jewish to join.)
