I’m sure some here are familiar with the plucky conservative Canadian from "Louder with Crowder."
In this clip, we see that he’s set up a booth on campus, with the banner "I’m pro-gun; change my mind." He excerpts two different conversations with students, from the respectable gathered crowd, about shootings and gun control; they both proceed largely the same. I think he does a fantastic job dealing with the idealistic—who also get all their info via big box sources. The clip/episode is sorta long at an hour; if you see him work with the first guy, you get tne gist of his method. I think there are some good things to emulate in his approach to the conversations. Recommended if you’ve got 25 min of TV time to spare.
