I just read your post. Where are the parents?
So go the churches. . .so go the families . . .so go schools. . so goes the the nation and we are heading in the wrong direction at record speed!!!!!!!
Like most Private Catholic schools it is a not a requirement to be Catholic to attend. Because this is in liberal Seattle I would bet a lot of the kids come from wealthy Protestant parents and probably a few parents who are not Christian but can afford to keep their kids out of a public school.
