With a scope you aim with the reticle (also with red dots with more than a point - so the ring around dot sucks) - with a good red dot you focus on your target. You want to hit the target and not the reticle - so why look on the reticle and not on your target. When you have a fight with snowballs, you look on your target - not on the snowball in your hand. Its that simple. A scope is good for targets at distance - but short range or fast moving targets are not the case for a scope. A red dot with only a dot and nothing fancy and the focus point on your target works together with your brain - cause that is, what our eyes/brain are/is used to 99% of the day. Our brain is simple - so keep your shooting simple. Its not too long an we were hanging around in trees searching for fleas in our fellows pelt. A close meet with an animal we hunt (or that hunts us...) is like a fight (same hormonal triggers in our body/brain) - i a fight, our brain goes back to a simple operating system - so keep your things to do simple. Use what is left in our mental possibilitys. Every hunter with iron sights will only see the front sight and a scheme of the target - there are no other things he will recognize after a close quaters battle like a charging buff. Its like a tunnel. The same with a red dot - with only a dot - but u will see your target clear and the dot will find the target automatically with some proper training.
