You are perhaps aware that there are many genres where the artists don't play instruments. Noise, ambient, electronica, trip-hop, audio collage (Negativland, EBN, etc.)...
I am not a pigfucker, however, you are making a lot of incredibly ignorant statements across the board, not just with regards to rap.
And I mean "ignorant" as in you don't know what the damn you're talking about, not as in "you're stupid".
