You've missed Steyn's point.
Which is: Let's not waste time defending Bundy, he isn't the point; let's address the larger issue of government over-reach.
The media has made so much of Bundy's alleged racism simply because it is a distraction from the central issue.
Steyn's stipulation isn't an accusation or a confirmation, it simply dismisses the relevance of the accusation.
Exactly right. I honestly don’t know if he’s racist or not - and I don’t care. What I care about is the feds taking his property by force, and his case and cause against them.
It would have been clearer to say that he did not agree that Bundy was racist, then say to stipulate to it. When you stipulate to something it means you do not want to argue about it implying agreement.
