I'll go out on a limb and predict that most of us on ETS would support knife rights since we probably keep a blade or two handy (I have two on me as I type this), so we would be preaching to the choir...
Perhaps the OP could post a link to the podcast in question? That might be useful.
I will allow a link to the podcast, but that's probably the point that political discussion regarding knives should stop unless/until I am overruled.
