>>show me how any of that says she's implying ALL rap music is that

let's look at the quote

"It.. along with most music nowadays.. is about falsenesses and vanities."

the "it" is rap music, you know this because of the context. The preceding sentence says:

"Don't be guided by rap. Gangsta or otherwise. Sure.. enjoy it.. adore it…as I do.. but realize this.. rap ain't about your civil or spiritual rights, baby boys and girls."

What else could the "it" be? And note she didn't quantify. She EXPLICITLY said "Gangsta or otherwise"

when she gets to "Rap ain't about your civil or spiritual rights" she's talking about all of it there too.

Next - just in case you missed it in the previous sentence she casting the net wider rather than reducing it to "some" rap

"It.. along with most music nowadays.."

Followed by her explanation of what rap (her word) is about:

It.. along with most music nowadays.. is about falsenesses and vanities. Bling, drugs, sex, guns and people- dissing.

After the list she summarizes the affect of it:

"Its giving you the message you ain't 'good enough' if you
don't have bling and ting.. and money. Or if you're not what it deems 'sexy'. (This is true of all popular music not rap alone. I know. Its tragically true of all popular youth culture the world over)."

The ONLY hedge is throwing in "popular" but that contradicts the previous.

If you can't see that, at best, she is sloppy then I can't call it
