#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. (I see your point- but it's wrong. I will elaborate in the next bullet).
#2 - Like the first statement- it's a mistake for you to speak factually on something so subjective. We're talking about art here, right? "Period" is especially offensive since clearly so many people disagree. Juvenile and simple are never synonymous. That's not to say they can't live mutually, but that certainly is not "synonymous". Period. Just the fact that people have agreed suggests he is delivering the emotion he intends to with his art. Unless, of course, you can tell me what his true intentions were with the lyric?
#3 - I'm going to make a fair assumption that you've lived a relatively privileged life. By this- I mean I'm pretty sure you didn't grow up in Bedstuy. I certainly don't believe that relieves him of his poor judgement, but I hope it helps invoke some situational empathy. Likewise, do you consider yourself not praiseworthy because of the mistakes you've made?
Edit - I assume a downvote one minute after a post is either accidental or negligent.
