In-house arguments

Are there questions that a non-Christian could ask that we should dismiss as being in-house?

In apologetics we want to demonstrate the solid foundations of our house - we have the best reasons to believe. We want to show how wonderful the house is - what the basic truths of the gospel are. But surely we also want to invite the non-Christian to see what life in the house is like? We want them to see that not only is the house secure and attractive to behold but that its the kind of house you want to live in.

So consider a question that seems to me to be about as in-house as you can get (and not a big one for most of us) - should women wear hats in church? They want to know, is this house a house where women wear hats at the family gathering? Which is all part of the 'what's it like to live in this house?' question. Which is all part of the 'Am I going to follow Jesus question?' And that one we want to answer.
