I don't like contemporary youth culture because it promotes nearly every ungodly thing imaginable!
Including although not exclusively: Alcoholism, drugs, sex, self-centredness, contenment in knowing practically nothing, laziness, self-righteousness, contempt for authority, gross emphasis on you rights and virtually no emphasis on your responsilities. It's a fundamentally self-destructive culture which will only lead people down the road to long-term sadness and heartbreak!
I am not perfect, 'tis true! However, taking a stand against these things is in my view important.
