Such hostility from meme, lol. You're right, though; his fan-base is primarily the younger teens, but you have to give credit when credit is due. His flow is impeccable and it never disappoints - not to mention how versatile he is. He in general, hardly ever disappoints.
A lot of his fans may be "younger," but they're also some of the greatest and most loyal/active out there. Don't hate, bruh.
