I stopped watching that video as soon as I noticed he'd framed the question as about what people think about legalization, and then changed the subject to whether it's constitutional. He apparently did it to point out that people don't think properly, which is supposedly only how he wants them to think. If he'd merely framed the question in terms of what people think of the constitutionality of legalization, they would have answered in that context.
But now we have a meta-level: let's talk about what other people talked about! Despite how silly it was!
