Don't 99.99% of those against abortion make exceptions? I only know of one group/organization that has no exceptions.
The exceptions should at least attempt at making sense. For example, if ones life is in danger, that would be an argument which
most 
would agree makes sense. These exceptions do not. Those who keep calling abortion murder, should not allow murder because the life was conceived by rape. THAT IS NONSENSICAL. Unless it is an argument based on psychological effects, in which case psychological effects should be recognized as an exception.
Keep in mind we are questioning republicans here, so you can even agree
