It goes both ways though. In blue states You have some kids that are taught nothing of world war 2 but are taught everything about the civil war and slavery. Among other trends in educating differences. There are many more. Extreme right / Extreme left are both bad. Any extreme anti-another ideology is just asking for problems.
I was educated in one of the bluest and most authoritarian states in the country (not that those two are necessarily related though the link seems to be getting stronger over time though that might just be caused by increasing extremism and authoritarianism in general). My brother got his education in a purple state that is probably one of the most anti-authoritarian in the US, maybe second to Alaska.
My issue is not so much with the typical left-ish ideology determining what we did and didn't focus our coverage on. My complaint is with the all that coverage having undertone of government doing no wrong, ever. I believe this to be somewhat particular to the state I grew up in, not necessarily left wing ideology (of the time).
We covered civil rights yet it was covered as though government was some savior implementing reform over the objection of backwards southerners. We got to see videos from the period but none of them had police dogs attacking protestors. We covered the civil war but not the failure of reconstruction. We discussed Jim Crow not in that context but in the context of the interwar period. I don't recall the KKK even being mentioned in discussion of the 1800s. The trail of tears, the Indian wars. That was all blamed on settlers encroaching on Indian land never any government involvement other than "protecting settlers". I never heard of Custer, Sitting bull, Wounded knee, etc was skipped. Discussion of the post-civil war US was all about industrialization.
It definitely goes both ways. I'm not sure "progressive" whitewashing of the past is any better or worse than "conservative" (in quotes because who knows what these words mean anymore) whitewashing but they're both not good. I wouldn't even say the particular whitewashing my education was subject to followed and particular mainstream ideology, it just religiously avoided mentioning anything that would lead one to one being skeptical of government.
I simply meant to expand on the GP's point that education does in fact have a large impact on ideology but that effect is delayed until that group start voting en-masse.
