Mr. Funk is a firearms instructor and all-round gun enthusiast here in Ohio. He puts out a variety of videos, with a decent-sized following, on lots of gun-related topics. I typically don't watch them all the way through because of the whole four-minute-attention-span-on-the-internet thing I usually have going on. This one, however, he hit out of the park. I don't know him personally and have never trained with him. That said, he nailed some key points for me, both as a student of the gun and as an instructor. Well worth the watch, whichever category you fall under, IMO.
