Why is that an issue for homeschoolers? Parents are responsible for the education of their own children, not the education of all children.
I work long hours so my wife doesn't have to work. We gave up an entire second income so we can homeschool. We sacrifice in many ways others take for granted.
My wife attends seminars, purchases and pours over books on raising leaders. She creates a custom tailored education for each child. We've purchased and read the following books:
The Well Trained Mind
The Well Educated Mind
The Underground History of American Education
A Thomas Jefferson Education: Teaching a Generation of Leaders for the Twenty-First Century
And many other books. We use the classical method for teaching. Click that link to get an idea of the rigorous education our children receive.
In all this, some freepers who are teachers think homeschoolers should take the time to try and correct what's wrong with public schools. Why? We are busying providing an education for our children our detractors can't provide. We are sacrificing years of our lives to give the best we can for our children, our legacy.
Apparently to some folks, homeschoolers still aren't sacrificing enough. Apparently to some folks, homeschoolers need to give more of their time, more of their life so other parents who don't care as much, who haven't sacrificed as much, can continue sitting on their butts and let others fight their battles for them. Get off your butts and get involved yourself.
These freepers who are teachers that say homeschoolers should try and correct the problems with public schools should shut up and remove the log from their own eye.
