President Kennedy- Early And Taking Requests

Why do pundits keep saying President Kennedy was late to the table of the civil rights movement?
I thought that was George Washington?
Didn't Washington fight the Revolutionary War based on principals of freedom and pursuit of
happiness for all Americans and on no taxation without representation?
Didn't he think labor theft was taxation?
Whose happiness could a slave pursue in the country where he or she was born?
Was Jefferson late? Did either he or Washington attempt to work out the birthright of their slaves
as citizens who lived and worked hard in this country every day?
Was the NAACP late during and after emancipation and so many regular lynchings?
Were not hundreds of years of those failures not dumped into President Kennedy's lap, triggered
by the murders of Emmett Till and countless SNCC and CORE sit-in youngsters after WWII?
President Kennedy did send needed troops down south when governors there attracted mobs
as they blocked entrances to schools directed to integrate.
He did ask Dr. Martin Luther King Jr. how the two of them could best interact to peacefully foster civil rights for all Americans.
He did drag the Mississippi River for young college student victims- repeatedly, agonizingly.
He did call Myrlie Evers when Medgar was martyred.
He did welcome Dr. King into the White House.
He did welcome the historic March On Washington.
He had begun talks on legislation to protect all our rights when that awful bullet took his life.
Unlike the then Vice President Richard Nixon, Senator Kennedy promised during the 1960
Nixon-Kennedy debates, to work on civil rights in our country.
When elected, he did just that.
President Kennedy was attempting to re-encode civil rights, and the rhetoric regarding the equality of all men into the U. S. constitution when he was prematurely cut down in his prime.
The United States hi-jacked -over and over again- the very wood citizens ever attempted to use to build an enfranchisement table out of the right to vote.
Were the civil rights leaders who weren't on the Edmund Pettus bridge when
Congressman John Lewis marched across it and into a screaming crowd backed up by
gun-toting, billy-clubbed badges late to the table?
None of our leaders gave us each and every right we deserved to exercise at the moment we asked
for them.  However-
President John Fitzgerald Kennedy helped build the table he came to early.
He invited all the rest of us to try to feel a tiny bit safer if we wanted to have a seat there beside him.
All hail, to Camelot, and to one of our most forthright civil rights leaders, President John F. Kennedy
