The prior question is how much difference is there between the probability of a woman being killed and the probability that a man will be killed. And I think that will be heavily stacked in favor of the man. If (reasonable guess) a man is five times more likely to be killed, the answer to your question could be that men are far more likely to be killed by someone other than a spouse - and yet his likelihood of being killed by his spouse could still be greater than a wifes likelihood of being killed by her husband.IMHO age needs to be factored in, heavily. The article seems to be wanting to strain at gender gnats, and swallow race/age camels. Without having gone to the source in this thread.
I see your point. That is a statistical possibility. On the other hand, men are much more likely than women to commit murder, which shifts the probability back toward men's being less likely to be killed by a spouse/lover/ex, unless spouse/lover/ex is a man.
I agree that age and race are better predictors of who is to be murdered and who will do it. As it were.
