Joe Rogan's Discussion With Matt Walsh About Same-Sex Marriage

I'm going by the video here. I know the discussion was lengthier than what's in the video just linked, but I've only seen some brief clips of the remainder of the discussion. I want to respond to the portion of the exchange in the video I linked, which has already gotten more than two million views. It's the portion of the discussion Rogan's YouTube channel chose to highlight. Walsh made a lot of good points, but I want to reinforce some of those and make some points of my own.
