Yes, the civil rights movement would have happened eventually but President Kennedy is the first president to REALLY get behind it and is, rightfully, due credit for that. I think many were caught off guard by his boldness in pushing civil rights and he had sort of faked them out when he picked LBJ for his running mate. LBJ had been a staunch segregationist (that turncoat!).
I do not revere the man any more than I think President Obama is my savior, or god.
I like the idea of remembering him especially for the civil rights progress made while he was in office.
And I like remembering the event as an important date in the life of our country.
Also, his speeches were inspiring to the young people of the day.
