I typoed, previously I had the post ready to go, but a freak "topic missing" error ate it.
As for your statement of their intent. I believe it to be true, but inspiring anonymous to work harder at being an insular misanthropic bastard... not going to be easy.
And, despite the fact that their interest in 4chan is unrelated to the boards, cliques love nothing more than the oppurtunity to exist in an insular environment where nothing might challenge conformity. At worst their own imageboard may provide a sufficient distraction that their interest is diverted from our fair fiefdom.
