I applaud LMTD for debating in the lion's den as it were.
While I was surprised that he didn't beat them down with "shall not be infringed" in the 2A, I can understand how that happens having been cornered myself in an unfriendly audience debate. In this case LMTD is arguing facts and law and the other side was arguing feelings. It takes no effort to ramble on about how one feels and really, how do you challenge that? You can't say, "Well, you don't really feel that way" or reply with "Your feelings are invalid". You have to counter with something that acknowledges those feelings (no matter how insane or you lose the sympathy of your audience) and then counter with a "but it doesn't matter how you feel because constitution" all while being nice and not looking like a bully beating up on a poor defenseless woman who just wants her community to be safe (so the audience sees it). In other words, she started off with the sympathy vote which had to dismantled politely. Further, LMTD had to do it off the cuff citing facts and quotes from memory with a camera in his face, a host who stated inaccuracies as facts and some audience hostility. Lastly, since she was mostly making emotional arguments disguised as rights (the right to "feel' safe without guns around as it were) there is little to attack her about for mis-citing something, however, LMTD has to make factual arguments without error to give room to be beat down later for a mistake and in that pressure cooker it is easy to start questioning yourself and wondering if you misstated something. We've all had those moments where someone asks what we just said, we response with "I didn't say that" but you really did because your mind was processing something else and it all came out wrong.
Well done, LMTD!
