They think, maybe rightfully so that this hurts the out group more than the in group (minorities), disclaimer: I'm a white male, except say that group is black or Hispanic, and have families that tend to vote the opposite way, then they're in effect hurting their own power hold by forcing more births. They're so worried about immigrants taking jobs what about the anti abortion baby boom making jobs more scarce in 18 or 20 years, and changing whole political landscapes?
