What a backwards way of characterising a style of vocal delivery. As I was reading your comment I was listening to the group 'clipping.' deliver the story of an uprising on an interstellar slave ship, the loneliness of the lone survivor drifting in and out of hypersleep for millenia, and the ship's computer realising the hate it had been taught for people with a skin color had no bearing in reality.
The GP talked about a specific person taking specific actions that they think was worth taking a stance against. Is your counter-argument to that highly pointed argument really to talk about everyone using a specific vocal technique?
Criticise a specific artist if they step over the line. Criticise someone like Immortal Technique for his 9/11 conspiracy bullshit and his rampant homophobia, but don't use someone like him to claim that somehow _all of rap_ should be discarded.
