I agree with most of the sellout definitions and no doubt that we have ALOT of sellouts. People not being true to what/who they are, where they come from, etc.
Let me make a quick point right quick on this definition that us blacks have on selling out...
You might see a brotha go to college, speak correct english, working in an office and wearing suits & shyt. Whats the first thing we do? Call him a sellout and he say he tryin to act white. But when we see a brotha on the corner selling dope, actin ignorant, in and outta jail, sittin back blamin the white man for problems he created for himself...we call that being real, or being black.
We need to cut that bullshyt out because if we keep thinking that like that, we'll never make it any farther in this world.
P.S...But sellout also means turning your back on your people for financial, or any kinda personal gain.
