Although I agree with you that there is a liberal bias in public schools, I personally think that the biggest problems with education are at the college/university level. I agree entirely with Trump that universities that exhibit clear bias and suppress opposing opinions should lose their public funding (e.g. no research grants, no development grants, etc.). I would also take away their tax-free not-for-profit status and tax ALL income to their endowments.
All the seeds for a “successful” college “experience/education” are planted before kindergarten in the public school system.
It used to be mostly on the university level HOWEVER these BASTARDS have discovered that they need to reach the kids earlier because if their parents are doing a great job before college it is harder to brainwash these kids!!! NOW they are starting with the teaching of propaganda in K-12 by the time they get to the university level easy peasy their minds are already mush!!!
