Why is it coming from "Reason" an alleged friend of freedom?
What is BS about this poll?
You can't fix a problem that you don't know exists. And you don't know the public's attitudes unless you go out among the public and measure those attitudes. Sticking your head in the sand instead, is likely to yield sub-optimal results.
Are the numbers valid? As someone who is not trained in statistical polling of societal attitudes, I have no idea. However, lacking other polls indicating otherwise, I'm inclined to tentatively accept their poll results until further evidence surfaces.
