Because it's a loaded question. Knuckle dragging mouth breathing drooling faggots like you hear that he wants to repeal the CRA and immediately assume it has something to do with racism. So he wants to say, "Yeah, repeal it," but can't say that because the majority of people are fucking stupid and won't be able to understand why.
In reality, he's likely against the CRA (I'm assuming we're talking about the 1964-ish one) not because of the good parts of the act, but because of the parts that are in violation of property rights.
PS-
I haven't watched the video or read the article. So the question of why he won't answer might be answered better in one of those. The above is just my assumption.
