That was my first thought. "Saving the planet" could also mean spreading the Gospel.
My daughter went to Catholic School from kindergarten through twelfth grade and currently attends a very conservative Catholic College. Like society as a whole, the faculty at the Catholic Schools that my daughter attended were made up of conservatives, liberals, populists, centrists, libertarians, and socialists, and she was never brainwashed into socialist/liberal ideology. In my opinion, the most important aspect of any education is learning how to think critically and objectively. Exposure to divergent points of view and differences of opinion are an important part of this process. Send her to the Catholic School, and with good parenting, you really have nothing to fear.
I would also keep in mind that teachers are constantly put upon by parents who take things the wrong way, often with incomplete information. Most educators, particularly low paid, but highly motivated Catholic educators, try to do a good job and work very hard. Every smart, responsible teacher has learned to be politically correct and at least somewhat balanced in presenting a point of view. There are a few idiots, but only a few in my experience.
Too often, I’ve seen angry parents treat teachers in a very shabby way. They can be condecending too. Usually, their anger is misdirected and misguided.
Bravo. Sending 4 kids through myself and we are not surrending their total education. They bring “climate change” up but we review homework so I will be the first to know when something funny is being pushed and I will explain to my kids. My 5th grader had a project on how to stop global warming and had 10 lines for extra credit in science. I told her to write “nuclear power” and leave 9 spaces blank. Never heard another word.
