I think focusing too much on the mistakes of previous generations does a lot of harm.

Notice it enough to not repeat their mistakes, but focusing too much on it creates animosity, and splitting up generations, making it so that young people dont listen to the old, and the old dont pass down anything to the young is exactly what "they" want.

Theres a lot to learn from the older generations, good and bad. Following the older gens without question isnt right, but we shouldnt let the natural inheritance of personal knowledge be lost.
