It is very difficult to watch the news reports on CNN and the other networks and not feel a need to respond to the atrocities that are happening before our eyes.
While our American society is a long way from perfect, that does not mean that we must stand idly by and watch genocide occur. A jury in Texas found the white man guilty of the heinous murder of black man last year. A Wyoming court sentenced a man to two consecutive terms of life imprisonment for killing the gay student. Seventy years ago there wouldn't even have been a trial for these murders.
P.S. This thread is informative. Where else could I have discovered that Brazil is a member of NATO? (No place that I am aware of.)
