Although Sanders often sounds like the crazy old man who can’t talk without yelling, like the prototypical uncle at the family dinner, his appearance at Liberty University is an excellent example of rational discourse about issues that tend to evoke emotional responses. The whole thing is quite long, and worth watching, but the question/answer stuff that starts at the 44-min mark really shouldn’t be missed.
