In one of my old answers, I challenged the accuracy of Luke with references. However once could say that Luke is right and the calculations and other references are either wrong OR there was a divine intervention. When answering questions which can be answered with extra-biblical empirical information, how do we handle the "fundamentalist" rebukes? I am not picking on fundamentalist specifically, but they were an easy practical example - sorry if I offended.
Don't answer questions asking how a contradiction can be reconciled by saying it can't be reconciled. There are some Christians who believe that every contradiction can be reconciled. If you're not one of them, then don't answer the questions directed to them. That's not a valid answer for those types of questions.
