Parents of children at a Catholic school are suing: their children, whose native language is Spanish, have been forbidden by the school from speaking Spanish to one another during the school day. School says this is its right; that it does no harm. Catholic schools clearly haven’t learned. They did this in Louisiana to French-speaking kids. They did it to kids on Indian reservations. It did harm. It was a ripping of kids from their culture. It is wrong. It’s just another power play on the part of an oppressive institution that wants total control.
