"I just.... don't like rap because of how people picture it now a days. It's all about bitches, sex, money, cars, vodka and whiskey, beer, wine, Kim Kardashian and vaginas..... or penises if their into that sort of thing...."
Defining rap as a whole is exactly what you're doing and yes, if you want to get your point across, don't leave half arsed responses that require you to connect near non-existent dots to understand your point. This isn't an elaborate plot in an anime or tv drama rather a discussion where points should be made as clear as possible, regardless if they are done in long paragraph or short sentence. Your first post was in no way clear on what your actual opinion was unless you specifically went out of your way to connect the dots, like I did.
Although I don't agree with all of his examples of good rappers, Examples were provided by Rem earlier consisting of rappers such as Snak the Ripper, Nappy Roots, Dan Bull, Professor Green. If you actually want to listen to good musicians in the genre, then checking out these artists will point you in the right direction.
Edit: It's 1:48 AM and I have school + an essay due tomorrow so if any more discussion on this matter continues, I will provide my input if I feel it is needed and more importantly, If I feel like providing said input itself.
