#1 - You're treating the quoted text as (I quote) "a quote". It's not. It's a small piece of a much larger whole.
Hmm - last I checked, a small piece of a larger whole IS a quote. Webster's definitively settles this in my favor.
#2 - No - there is no subjectivity involved in the claim that his lyrics are 'juvenile' and 'simple' especially when the man himself has said so on several occasions, both in verse and out. (See the song: Moment Of Clarity) If the artist himself says he 'dumb downed' his lyrics, I think its purely factual to then say his lyrics are 'simple'.
#3 - Pardon me, you don't know a damned thing about me or how I grew up. So no, your assumption is not fair. I've seen the gutter in my life. I've lived in places that I gather you are only familiar with through Jay-z songs. So forgive me if I take a particular offense to this comment.
Situational empathy? Are you kidding me? I suspect this kind of careless, 'there are are few better options' mentality stems from a brutal ignorance of what inner-city life is really like. So let me just help you out by saying there are thousands of kids from these terrible situations, (many of whom I work with weekly), who do not deal drugs, who stay in school, who pursue scholarship, who do not idolize Jay-z and his calling cards, thug-culture, gun violence, promiscuity, drugs, and death. Unfortunately for all of us, these kids are in the vast minority.
