Stating the obvious.
Some recent Der Movement correspondence leads me to state that my (sometimes harsh) criticism of (White) racial nationalists is business, not personal (*). And, of course, I’ve already stated, multiple times, the over-the–top rhetoric that accompanies some criticism is tongue-in-cheek and not to be taken purely seriously. But the serious criticism, which should be taken at face value, is business: a different view of ideology and of the direction that the “movement” needs to move. There is always – even if weak – an underlying attitude of all belonging to “this thing of ours” and therefore at least some minimal “professional courtesy” is in order (again excluding the obviously sardonic mocking of “movement” Nutzi lunacy).
With respect to individuals who are not racial nationalists, my criticism may very well be personal as well as business – Derbyshire is a classic example. These people are beyond the pale of respectability as defined from a racial nationalist perspective, there is no underlying sense of community, and some of the harsher criticisms are not necessarily tongue-in-cheek.
All of this would seem to be (at least intuitively) obvious, but I suspect it is not.
