I don't. Lucas himself has acknowledged the EU. I don't see the problem everyone seems to have with it. He clearly said he has no problem with it in the interview Mr. Bungle posted. I think what you are referring to as "canon" is what Lucasfilm calls "G-canon," which are the films, novelizations, and radio dramas. EU is called "C-canon." It's all canon, just on different levels. Nathan knows, as his 1,000 + page timeline is based solely on their canon policies.
