If this were true then why would FET not be the prevailing view?
Change takes time, and we do have a schooling system that (in our case) is tailored towards raising good Tory voters, and not people who think critically.
The tall order for FETers to change the prevailing view goes much further than just for folks in the UK.
The prevailing RET view is also true in China, India, Japan, S. Korea, N. Korea(!), Iran, Egypt, Brazil, Norway, Iceland, Singapore, Belorussia, Kazakhstan, Armenia, Israel, Thailand, Austria, The Czech Republic, Russia, Portugal, Ethiopia, the UAE...(well, one could list every political entity because in my understanding none exist in which FET is currently the prevailing view, and indeed, it's a phenomenon that only exists in a handful of countries at the moment right now anyway, even in small numbers).
My substantive point here isn't just that it goes well beyond 'fixing' the school system to stop raising "good" Tories in Britain. All of these places have quite diverse schooling systems, and yet
all of them produce citizens who generally believe in RET, not FET.
Change is indeed hard if you're going against literally the whole world...
