Once again, ignorance is not the reason for fascism, and you can't educate your way out of a situation which you didn't get into by ignorance.
Believe me, fascists know exactly what they're doing, and they often know history quite well. You can't inform them. They already know.
Education has its importance, particularly in reaching those who aren't yet convinced, but you can't convince a bigot or a fascist to give up their path through reason. They don't care about hypocrisy either.
And saying, "People wouldn't be bad if they were better educated," is both incorrect and egotistical. There are plenty of well-educated evil people, and by positioning education as the divider, you imply that your side is smarter and therefore better.
Education, specifically public, public-funded, and liberal (from a classic not a political standpoint) education is also valuable because it gives children the opportunity to meet other people. It gets them out of insular family groupings. That's why fascists want to control education. Not because a poorly-educated populace is inherently less moral, but because they want to isolate children and indoctrinate them.
Some of this stuff is arguable. The conclusion isn't. You can't educate your way out of a fascism. It is necessary but insufficient.
