When the Bishop refuses to acknowledge the value of the other services provided by Planned Parenthood, services many of those women cannot get elsewhere because society doesn't provide for them to get them, then he, too, is dealing in obfuscation.  

The "core" issue is not abortion but providing perfectly legal health care services to women who have no place else to get those services, including contraceptives, health screenings, and abortions. Those other services matter. 

In this case, the issue of "obfuscation" depends on where one stands.
