Because, anyone who isn't racist simply wouldn't respond to a multiple choice question that doesn't provide an adequate answer. Saying you're not racist is like saying that you're not gay. The response raises more of a question than it answers.

@Facci in response? your logic is clearly flawed your premise that " anyone who isn't racist simply wouldn't respond to a multiple choice question that doesn't provide an adequate answer " is simply irrational.

" Multiple " choice questions MUST give degrees of latitude in order to be fair and reasonable - and can ONLY be deemed as such when either end of the desired response can be achieved.

So instead of asking ( for example )

DO you have oral sex with gay men

(A) very often
quite often
not very often
not at all

( given YOUR logic ) the choices would be assumed as:

(A) very often
quite often
not very often

You will notice that there is no way to answer such a question in the negative - given the preposition that ( in YOUR opinion ALL men ( to some degree ) have oral sex with gay men.

I submit that your logic is deeply flawed and is based on some kind of interpersonal communicative skills deficiency and social misalignment.

The AIM of multiple choice questions is to " sample " responses from both ends of the spectrum - at both extremes - NOT to LOAD a question with the possibility of answers that can only lean towards one single outcome.

P.S. - if you noticed....I DIDN'T actually vote on your question - as it CLEARLY had no option that suited a desired response. HENCE my initial comment to you.

@ROGAN You're thinking way too hard about this. I appreciate your intensity, even if you don't appreciate my sense of humor. Cheers.

@Facci Sorry mate - its the IQ and if it was a sense of humor comment, yea, I totally missed it - KUDOS! - well played
