I should have clarified - my rant wasn’t meant to be towards you... your 10 yard statement just inspired me.
That said, I think the dot is an advantage for more than just “shooting”. The ability to maintain a single focal plane is a big deal even within 10 yards and I think that’s huge even for the average shooter. At the same time, I think the practical side of dot use (vs competition which has a more established history) is still new enough that we don’t have the answers yet as to what’s easier for a brand-new shooter/gun carrier to learn to do in a fight.
Most instructors are getting motivated and at least somewhat experienced students (with some exceptions) and like you mentioned, dedicated dot users for defense (ccw and law enforcement or military) are very much still in the minority.
Makes for fun times.
