Indeed, this makes me wonder just how genuine the question was in the first place and whether Craig really believes that it is possible he has blind spots. This said, this response should not be at all surprising. It is a sad reminder of the way that we are often slow to learn the lessons of history. Take for instance this quote about slavery, made during the period leading up to the American Civil War:
If we prove that domestic slavery is, in the general, a natural and necessary institution, we remove the greatest stumbling block to belief in the Bible; for whilst texts, detached and torn from their context, may be found for any other purpose, none can be found that even militates against slavery. The distorted and forced construction of certain passages, for this purpose, by abolitionists, if employed as a common rule of construction, would reduce the Bible to a mere allegory, to be interpreted to suit every vicious taste and wicked purpose. - George Fitzhugh, 1857
Sounds familiar, doesn't it? It's just like the accusations levelled at people who say that the Bible allows women to be ministers and that there is no prohibition on monogamous homosexual relationships. Surely this should give those who make such accusation stop to pause for a second. You'd hope so, at least.
The thing about a blind spot is that one is blind to it. That is, if one knew that they had a blind spot, how could it be a blind spot anymore? Of course, it is true that once something unpleasant comes into one's field of vision, one could take steps to close their eyes and imagine that it is not there. However, whether or not those who use the Bible to perpetuate a sexist and homophobic agenda are doing so in a wilfully blind manner is not for me to say. Usually, I will try to attribute the best motives to someone, and as such, I'll suggest that it is merely ignorance and not contempt for Scripture that is their fault. This said, we must be mindful of the profound damage that has been done both to women and homosexuals in the church (and homosexuals outside the church) and the name of the church itself. For this reason, we cannot afford to turn a blind eye and must actively fight intolerance in all of its forms.
