Then explain the merits of his argument if you are capable of anything more than being a crying child with delusions of adequacy.
What? Do you have a brain tumor? Asking someone to "explain the merits" of an acknowledged error is analogous to asking to prove a negative.
The issue here is not defending Akin's mistake, it's finding out why you have such a pathological need to make a pariah out of him for it.
Seriously, your histrionic rejection of anything that even hints at being exculpatory for Akin is making you look like the Child Protective Services Gestapo trying to convict the innocent to keep from admitting they're on a witch hunt.
