Nicely done.
I try to stay out of this debate for many of the reasons you do. I was taught quite the same as you and I learned when and where, but I refrain from teaching others this way. In today's world it's not codusive(spelling) to any of us to teach this habit. I apologize to you as I've used one of your lines from a previous video many times saying I do it because I'm a lazy fook. Im currently trying to teach a young man to be my replacement and I am in the constant battle with him over the one handed thing. I've done it since day one but I feel it's my responsibility to teach him better than I was taught. The problem is, I don't know any better. I do it when I need to, but I could do things a bit different to make it "safer" at times. I took your video and his blog as a moment to reflect on myself and how I affect the guys I work with. Hopefully something good came of it.
Stay safe my friend
