If the Republicans in the GOP-dominated legislature get their way, students in North Carolina sex education classes will be taught that abortions are a cause of future pre-term births.

You know who says that is true?  Me neither.

You know who says that's not true?

The World Health Organization
The CDC
The American College of Obstetricians and Gynecologists
The American Academy of Pediatricians
The American Public Health Association

Now, there may be some contrary evidence that abortions heighten the risk of future premature births.  But all that means, taken as a whole, is that the evidence is inconslusive.  You shouldn't teach thing which aren't — or that you know might not — be true.
