lol ;) well played
IMO, the real radicalization isn't taking place as much in the grad programs as it is in the undergrad ones. Grad students, particularly military members, tend to be older, more experienced, more critical, and more willing to push back, It's the undergrads that get it the hardest, and the most.
My hypothesis is that most of the schools on that list have very few "out and proud" conservatives. By taking away the .mil folks, you're even further reducing the number of centrist-to-conservative minds at those schools, and undergrads and grad students with a centrist-to-conservative bent will have even fewer role models and mentors.
At the same time, if there isn't a chance for growth and development out in the force between undergrad and grad school (i.e. straight to grad school after commissioning), then those minds are often ripe for manipulation. If I were in charge, there would be no one that the .gov paid to go to undergrad school go straight to grad school after commissioning, unless it's something like med school because it takes so long to get through it. Everyone would go into the force first, serve the entirety of their first commitment (normally 5 years) and THEN you can compete to go to grad school. By then you have some life experience, but more importantly you actually know something about the military, and probably have a better appreciation for American because you'll have been to places in the world that aren't some kind of glorified curated internship and know that America really isn't that bad in comparison. You'll also have a fully-developed brain and be able to resist the kind of political indoctrination that drives you to do produce things like this:
