Surprisingly my three years in a Catholic HS saw overt Marxist instruction on the part of three guys in the Soc St dept and five in the Religion Dept. This was back in the days of Reagan, El Salvador,Pershing Missiles etc. I was quite a bit more liberal back then but I called these folks on their blatant political indoctrination and was told that they were following Catholic Social Action and i should as well. Such a situation has never occured in my 22 years with the NYC schools. I've had plenty of arguments but for the most part the kids are left out of politics. These things may happen in other places but I've been in two schools and my wife inthree and that's been our experience.
In my school in NJ there is not one teacher under 35 who is not a total liberal leftist. They were all brainwashed in college.They are like sheep.
