Please look at my posts in this thread and tell me where I have said anything against the general success of homeschooling. I have not. I fully acknowledge that homeschooling can be quite successful.
I made the point that homeschooling is, on average, superior in practice to public schooling, and I posted a link to research reports. The evidence from those reports is not "subjective." And yes, with that evidence, I am criticizing public schooling and saying that it is generally inferior.
