Agreed, OP's post was reductive and sensationalist, to the point that it contributes to the problems it critiques. Our nature as people hasn't changed much, the internet just prevents much of the curation of voices that occurred before it existed.
It's not reasonably possible to rid ourselves of the internet, and in fact I think it's a net Good. The issue going forward is to consider and teach responsible internet use for not just young people, but everyone. Most of the shitty, intentionally hurtful things I see on the internet don't come from young folks, but from adults trying to inflict harm. People like that have always existed, and are the real problem in these cases.
It's 6 of Dr. Seuss's books, and ones that most people haven't heard of. If you actually look at the content of the books, they are clearly racist and demeaning to those they make caricatures of.
And in any case, it was not a sudden "canceling" or anything approaching that. Seuss's estate, managed by his family, made the decision after much deliberation to cease the publication of only six books due to the content. You could even see it as an anti-cancellation - Seuss's family wants to avoid him being associated with the obviously racist content of some of his work.
