I won't say all, but good portion of buraku discrimination is driven actually by these buraku rights group. There are bit of concessions exist (via affirmative action for instance) and there are some incentive that some of those groups want keep this issue alive for the sake of that, rather than try to actually resolve the issue somehow. Like you said, a lot of people don't care, especially in urban regions, because the concept of buraku itself is fairly foreign to people living there. Maybe this is but more prominent in rulal areas.
