There is a world of difference between a "campaign of political and social indoctrination" and "worldview that doesn't hold up to the barest of scrutiny."
Unless you're referencing the clear bias in universities in the US founded by GOP folks upset their particular indoctrination (religious or political)doesn't stand up to scrutiny, then not that were there were an organized campaign of political and social indoctrination for leftists that academics would lead the charge to attack it and get funding to both study it and find alternatives to it.
Turns out when you encourage people to think for themselves they do.
