Just about every generation has some horrific evil that it must fight. For the Democratic Party today that evil is carbon dioxide emissions. For the rest of us, it is an ideology that teaches that its deity is sanctified by the blood of innocents, just as the Aztec deities were.
History will see that clearly. And judge accordingly.
Just how clearly remains to be seen, considering that the greatest evil of the last generation (communism) is for the most part depicted by historians (read: academics [read: far left]) as having been either a) an overblown threat or b) not that bad, really.
Of course, at this rate, we won't be the ones writing the history of this generation.
That is, after all, a privilege reserved for the victors.
