Why engage in this folly, when I already said I am not going to debate individual subject matters?
Fair enough, your choice.
First, such would be struck as derails because individual topics already exist.
Not sure about that. It all falls under the umbrella of education, which after all is supposed to be about teaching students about reality. The issue is that there are many aspects of reality with which conservatives are unhappy -- it doesn't conform with the Bible, it's something they find embarrassing, etc. -- so they want to throw the blanket of "liberal bias" over those topics and remove them from the curriculum.
Second, the fundamental issue here is with the policies of DeSantis, which revolve around a general concept of preventing the sort of irresponsible teaching that we supposedly agree should be avoided.
Here is the disconnect. DeSantis isn't trying to remove "irresponsible teaching" from schools. He claims he is, but that's a lie. What he's really trying to do is prevent kids from learning things that he doesn't want them to, because it would make them more knowledgeable and able to think critically, and therefore less likely to vote for him and his party. It really isn't any more complicated than that.
I am content that most of us agree that there are irresponsible teachers on both sides of the fence...
Agreed.
...that this should be avoided...
Probably impossible as long as teachers are humans. Besides, I'm not sure it's necessarily a bad thing if the biases more or less cancel themselves out. And in any case, there's very strong indication that conservative bias has had a far more profound impact on education than liberal -- I cited several examples in my previous posts.
...and that curricula should be well-regulated.
This is the scary and dangerous part. Well-regulated by whom, politicians who have no training in education, and whose ultimate agenda is not to eliminate bias but rather to prevent students from learning about a wide variety of subjects simply because they wish reality were different?
After that it is just the never-ending debate of liberal and conservative values.
This is the most disingenuous statement of all. It's not about liberal vs conservative, it's about reality vs fantasy. I'm sure DeSantis would love to have people believe it's about ideology, to get people to believe it's simply a political issue rather than what it really is, which is government-enforced ignorance.
