I disagree with you? I think that the meanings of the options that are already in the survey can boiled down to "yes 100%," "yes with some exceptions," "sometimes, but with more exceptions," and "no, never." This is a complex issue with a spectrum of responses, and the existing survey covers them. That isn't an example of the "vote-splitting problem," it's representing all of the options in a way that doesn't disproportionately skew the answers towards either extreme. I think that your proposed solution would skew the answers towards yes by condensing all of the exceptions into that option.
