Stacking the Deck

An interesting piece from the AP about how home schooling science
textbooks lean towards creationism:

Those who don't, however, often feel isolated and frustrated
from trying to find a textbook that fits their beliefs.

Two of the best-selling biology textbooks stack the deck
against evolution, said some science educators who reviewed
sections of the books at the request of The Associated Press.

Geez I wonder how the parents of children who attend public schools
but have questions about evolution feel when they find out the public
school system has stacked the deck against teaching any flaws in
evolution? I wonder if they feel isolated and frustrated?
