I tell this to every parent I know. Especially right now with wuflu and crazy-lefty-teacher anxiety so high.

Private schools are 'endowed' (read: quietly funded) by outside interests that mainly promote One World agendas. My kid was offered travel and seminar access to the most creepy, backwards-values events; saving the world through feminism/saving the world through funding training (from training pdf: Don't tell people where their money will really be going, because the goal is more important than honesty).

I tell people to shop the Independent Schools because they are as unique as the people that run them. Some are ran by SJW's but most are run by open thinkers who are more attentive to their parent group's goals and values.
