It's like they're actively trying to bung up their own chances.

First, we have Todd Akin self-fellating in public with the speech about "legitimate rape" not causing pregnancy.  Now we have yet another Republican Senate canditate, Tom Smith, equating pregnancy from rape with pregnancy from "oops!  shouldn't have had sex without some form of contraceptive!" casual sex.

Okay, pro-lifers.  You can't seem to figure out an argument that isn't going to push the "God, you're an insensitive twat!" buttons for the nation, so here's your argument that will work.

1.  Remind everybody, every time you open your mouth about it, when the heart starts beating and the brain starts working.

2.  Remind people that abortions are killing girls (committing hate crimes against women, if you can bring yourself to cater to the part of the crowd that you need to convince), and refer to all babies with a female pronoun, not neuter, unless and until shown an ultrasound that shows a penis. 

3. Show ultrasound videos of babies playing--and they do that pretty darn early.  

4. Do not, under any circumstances, downplay the trauma of being raped.  Do not imply that there is such a thing as not legitimate rape, and do not conflate pregnancy from rape with pregnancy from stupidity.

And guys?  If you can't do these simple things, then shut the fuck up.  You're not helping your case.
