It doesn’t make you a Fudd, however since you admit you were chasing the dot, and therefore not employing the optic properly your opinion on this doesn’t really have any value as to irons vs optics.
You do however raise some common issues. My agency has issued optics on carbines for about 15 years (Eotech and Aimpoint H-1) but Like most agencies, we issue and primarily shoot pistols with iron sights. As such I have seen several shooters express the exact concerns you raise about RDS on the carbine and every time we have determined it is operator error, I.e. focusing on the dot like it is a front sight and “chasing” the dot.
This is a software problem, not a hardware problem. IME taping off the RDS and working with it as an occluded RDS sight helps force shooters to employ a target focus and helps them “get” properly employing the optic much better than any explanation.
It is similar to placing tape over one lens of shooting glasses to help shooters transition to shooting with two eyes open.
There are a small percentage of people whose eyes have problems with accommodation and who are unable to use occluded eye gun sights but this condition is relatively rare. I believe we have a thread on it somewhere, possibly in the RDS section.
When employed properly, the RDS is of greater benefit to those with vision issues than to those with 20/20 or better vision but all sights (iron or RDS) do Is show you what the gun is doing. No sighting system can make up for poorly executed fundamentals, your “crutch” argument is invalid. For someone who knows how to operate the firearm the RDS simply provides more information about what the gun is doing.
For LE agencies which may have an aging workforce in their 40s or 50s This is a real issue. For example, I had to begin wearing glasses about five years ago due to age related presbyopia. As Mike Tyson says, everyone has a plan until they get punched in the face, So I make it a point to shoot our pistol qualification course both with and without RX glasses. With uncorrected vision my scores are noticeably better with the red dot then without. You may recall that one of the best shots among the FBI Agents in the 1986 Miami shooting was a SWAT team member who was rendered ineffective after losing his RX glasses in the vehicle crash that initiated the fight.
As for the RDS being more suited for offenses rather than defensive use that argument is also invalid. The RDS, particularly on pistols, is a target focused siding system. As such it is more appropriate to reactive or defensive use then iron sites which require shifting the focus off the threat. In fact one of the arguments for law enforcement transition to RDS is that a threat focused sighting system allows the officer to stay focused on the threat and therefore gather more information about whether to shoot or not to shoot.
With regards to offset in CQB/CQC Environments that is a training issue. If You put in the work it’s not an issue. Of course,we Americans don’t like work so there are also multiple hardware solutions to this. The 6 o’clock hash mark of the circle dot reticle found in Eotech, SIG and Holosun optics as well as the Vortex UH-1 and the latest version of the MRI All correspond perfectly to the offset at close range with AR15 type weapons.
