i haven't read much of the thread after this as i suspect it likely devolved into another shitshow. i'm also certain that a number of posters probably offered a lot of criticism of the university of austin ethos and its mission statement and founders (deserved imo).
i would just say while that meritocratic message may be something that superficially resonates for you since it seems you've apparently found some frustrations in the conventional university application process (though i think the characterization of said process in the tweet betrays the ideological bias driving the tweet)...as someone who prides themselves on seeing both the bigger picture of things as well as unmasking propaganda messaging as you do, i'd caution you to view this as anything more than just marketing material and ideological red meat to disenfranchised kids and parents who wonder if they will get a fair shake (dei/affirmative action dog whistle) and further integrate them into said mentality. it's also just pure marketing for an organization trying to get off the ground and get some momentum to reach critical mass in order to be taken seriously and transition from "pre-revenue" to "post-revenue." i don't find it particularly resonant. moreover, if your kid makes a 1460 on the sat, they will not struggle to gain admission into a number of traditional, prestigious schools so it's not like they are offering some sort of lifeline to the otherwise discarded.
"courage to join the first ranks of our truth-oriented university" pretty much gives away the game.
but perhaps it will be a good landing place for your kids. who knows? give it a shot and follow up.
in the last three years, i have hired graduates of upenn, umich, ufla, utexas, and tamu...and shockingly, other than the agro, i'm surprised any of them can get themselves out of bed in the morning and tie their own shoes.
