Some would say pretty much the same thing about the Republican party. The truth is that both parties have their extremists, and these days it appears that those are the ones being listened to. It's too bad that we can't take the best ideas, policies, etc. out of both parties and use those things to form a third party, compromising in areas where compromise is needed.
Possibly a couple of decades of "experts" telling people how to raise their children, what they must do, what they must never do, etc. and that coupled with the fact that in most household both parents work outside the home in order to provide for their families and so have come to depend on daycares, schools, and after school programs to provide the majority of the daily care/teaching of their children has played a large part in the mess we're all seeing. We now have younger adults, young adults, as well as those just reaching adulthood, many of whom believe they are entitled to be given the very things the rest of us worked for, and worked to achieve.
