Many, many times. I was thrown out of Social Studies 30 because I interrupted a teacher’s anti-American rant with some facts. She claimed that America was a nuclear terrorist nation because it had dropped an atomic bomb on completely innocent people. I pointed out that they were, in fact in a declared war, and she said, “That was with GERMANY!” I reminded her of Pearl Harbor and the subsequent declaration of war, and she replied, “Ok, technically it may have been a war. But it was NOTHING compared to the war in Europe.” To that I started reciting casualty counts in the battles of Okinawa and Iwo Jima, and that’s when I was kicked out of the class for being ‘disruptive’.
I had an english prof who was so committed to seeing everything through the lens of feminism that I cynically wrote my final paper on ‘Pride and Prejudice’ - a book I didn’t even read. I just prattled on for 1000 words on the poor state of women in Victorian England, and got an A.
In grade 9, my son was forced to watch an execrable propaganda video called ‘The Story of Stuff’ which was essentially a far-left screed against corporations and global capitalism, dripping with scientific and economic errors. Just remember kids, all you need to know about factories is, 'toxins in = toxins out!"
In grade 12 social studies my kid was taught that the difference between the left and right was that the left is altruistic, which means they love their families and the little children of the world, while the right is materialistic, which means they love money and power. Wrong on just about every level. Then immediately after being primed with this bullshit they had a ‘mock election’ in which almost all chose to vote for the cause of puppies and children by voting for the left-wing candidate. I have rarely seen such blatant manipulation. That teacher also had posters of Mao and Che Guevera in her classroom.
When I went to college, we had to take ‘breadth’ courses, and being in science I had a number of arts and humanities electives. Now, my kid goes to the same college but many of those electives are forbidden unless you first take two social justice classes to ‘prepare’ you for them. So, no anthropology or archaology or sociology electives for him… All fall under the category of programs too dangerous to take until your mind has been put through the social justice filter first.
Also, as a math major he of course had to take the mandatory course in sexual harassment and microaggressions that all freshmen have to take now…
Anyone who doesn’t think public education is heavily biased against conservative and libertarian thought is living under a rock.
