HRSA doles out the money via block grants to "community organizations" (church based, naturally) that each these programs.
There have been a few members of congress that have done a great job of ferreting out this fraud, but their efforts have been mostly for nothing. Even Obama supports the continued funding of these fraudulent schemes. It's basically paying the conservative Christian community to teach our children complete and utter bullshit about reproductive health that in most cases is highly misogynistic.
Here is some direct examples of the shit your tax dollars are helping spread:
One curriculum says that the popular claim that condoms help prevent the spread of STDs, is not supported by the data; another states that n heterosexual sex, condoms fail to prevent HIV approximately 31% of the time; and another teaches that a pregnancy occurs one out of every seven times that couples use condoms. These erroneous statements are presented as proven scientific facts.
One curriculum states that 5% to 10% of women who have legal abortions will become sterile; that [p]remature birth, a major cause of mental retardation, is increased following the abortion of a first pregnancy; and that [t]ubal and cervical pregnancies are increased following abortions. In fact, these risks do not rise after the procedure used in most abortions in the United States.
Many of the curricula present as scientific fact the religious view that life begins at conception. For example, one lesson states: Conception, also known as fertilization, occurs when one sperm unites with one egg in the upper third of the fallopian tube. This is when life begins. Another curriculum calls a 43-day-old fetus a thinking person.
One curriculum teaches that women need financial support, while men need admiration. Another instructs: Women gauge their happiness and judge their success on their relationships. Mens happiness and success hinge on their accomplishments.
