The problem with any poll that says yes and no, is that it doesn't really answer the question that the poll is trying to ask.
If I made a poll that asked how many on this site are sexual deviants and the choices were yes definitely, no definitely and "yes and no". It would only tell me that all were either sexual deviants or liars. The problem is the "yes and no" people would skew the vote so I couldn't tell exactly how many liars there were.
Exactly my first response. I answered "Yes and no", but I only took one class. Is being told or shown how to do something count as a class?
