That seems to indicate that I would not be considered a relevant data point in your survey and would have been ignored or discarded.
Also, that still doesn’t solve the problem of simplistic definitions of complex issues.
For instance, if someone believed in equal pay for equal work, but was opposed to abortion, would that make him pro-feminist? anti-feminist? both? neither? How can he rate himself on a point-scale of any type without a better definition of the terms?
