Um, when you say "free", what you really mean is funded by the American taxpayer. Right? Conservatives are well educated. Your problem and the problem of most democrats and leftists is they don't know the difference between education and indoctrination.
By free, I mean no charges to the student. Just like K-12 education
The fear mongering about indoctrination is just more Conservative War on Education
Typical Conservative paranoia
Teachers are out to get us
Scientists are out to get us
Historians are out to get us
The media is out to get us
