I've been thinking about some possible conversion projects lately, and I started tossing around the idea of Chaos tainted Tau. I've read several other posts on this subject on a few other sites, and it seems the general objections are...
1) The Tau barely register in the warp: As I understand it, so do humans, at least that is what the Eldar claim. Either way, I never knew the chaos gods to be too picky. Besides, they're not really interested in your souls. Khorne relishes in slaughter, he doesn't care if his followers are killing or dying, so long as there is bloodshed. So why wouldn't he accept any bloodshed offered by Tau? Nurgle only cares for testing new decay and corruption. So why wouldn't he be interested to see how his various plagues on the Tau? Slaanesh only seeks new pleasures, so why not seek to please his/herself with the delights of the Tau? And Tzeentch is the Changer and corruptor of all, so why not play with the Tau?
2) It's never happened before: same could be said of the Space Marines until Erbus fell and took half the legions with him.
3) The Tau have no psykers: Neither does Khorne, then again Erbus wasn't a psyker either, and let's not forget that the Death Guard didn't as well. In fact not even Tzeentch needs a psyker to worm his way in. How many stories are there about Tzeentch found a way to corrupt through technology.
Thoughts?
