What did the. growing popularity of malcolm x black power and the. black. panthers show about the. civil rights movement by 1965

It showed a shift to a more aggressive stance in the fight for civil rights.  Previous civil rights advocates like Martin Luther King advocated reconciliation and non-violence.  Malcolm X called for a war against their oppressors as well as a separate Black nation.  The Black Panthers also had a similar belief which led them to come in conflict with law enforcement.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
