"In the present dangerous crisis, Negro Americans, as well as all other Americans, must make sacrifices to meet the emergency. At this time and this time only, we dare not confuse the issue of prompt preparedness with a new social experiment" FDR 1940
"The presence in military units by persons who, by their acts or by their statements, demonstrate a propensity to engage in homosexual acts, would cause an unacceptable risk to the high standards of morale, good order and discipline and unit cohesion that are absolutely essential to effective combat capability." Sen. Nunn 1993
Bigotry seems to hid behind "the military is not a social experiment". It was wrong in 1940, it was wrong in 1993 and it is wrong in 2019.
