I’ve addressed this issue at length in a Feb. 19 entry on the LewRockwell.com blog
I would have expected you would be able to go to Rockwell's site and pull up the information but I'll put the very end of it here for you. But I would recommend giving the whole statement a read to get even more insight
For these and for no other reasons, and in this context, have I had an intermittent membership in the League over the years. I have played no day-to-day role in the organization and I am responsible neither for the comments of any other member nor for the politically incorrect statements I am told can be found on the League's site. With the passage of time the League has begun to emphasize the importance of preserving Anglo-Celtic heritage, a position I am expected to repudiate. As an Armenian and not Anglo-Celtic at all, I nevertheless see no reason to: why should every group except Anglo-Celts be allowed to preserve their culture? (As for the group's "racism," a word that is thrown around at anyone who looks cockeyed at Jesse Jackson, I find it revealing that white supremacist organizations have repeatedly and vocally condemned the League.)
That should be more than enough to satisfy anyone's curiosity.
2) He does not deny, as I understand it, any of Max Boot's specific quotations from him regarding race.
3) To say one is only "intermittently" in the KKK or a Nazi is hardly a ringing endorsement of one's position. To say one is not "responsible" for the comments of the leadership one supports is plain silly.
