IME, Denver has some of the most self-important TSO's in the country. There are a lot of retired military personnel working that airport, and I've seen power trips past counting in the lines there. It does not surprise me at all that this incident happened in Denver.
Oh, and as to this:
But to close my thoughts, let me ask you something: would you want to get on a plane with your children/parents/SO without EVERYONE being checked, including those in wheelchairs?
I'd be absolutely fine with it, because I am realistic about the actual level of risk. Research outside the US has indicated that random checks work just as well when combined with behavioral observation. A disabled individual with Pre-Check, in particular, should not need to undergo invasive screening.
The VAST majority of passengers are not planning on doing anyone any harm, even if they do happen to be carrying a Leatherman tool or a phillips-head screwdriver (or to give a nod to Star Wars Day and Peter Mayhew's run-in with Denver TSO's, a custom-made lightsaber-shaped walking cane

You simply cannot eliminate EVERY person wishing to do harm, because the truly motivated will find a way around existing checks, whatever they may be, and to imply that the standard screening process is the primary means to "keep us safe" is disingenuous at best. Billions of dollars have been wasted on poorly-vetted technology that was ineffective, when it might have been better spent on salaries, classroom training for LEO's and in support of the intelligence community. There is risk inherent in any kind of travel, but even without the TSA standard screening process, you are hundreds of times more likely to suffer a tragic fate in an automobile than you are in a commercial airliner.
We've been conditioned by the media and by Homeland Security to harbor an unreasonable fear of terrorism, when the truth is that the risk of that happening to any given person is actually infinitesimally small in comparison to being killed in a traffic accident. We all need to step back and regain our sense of perspective.
