Why would you want to hide away your religious materials to satisfy people who are so incredibly rude that they insult your home to your face while accepting your hospitality? To anyone who does so in the future, I recommend saying coldly, “I’m so sorry that my home is not up to your standards. I wouldn’t dream of keeping you. Here, let me get your coat and we’ll call it a night.” Show them to the door and then resolve to find a better set of friends. (Of course, if they come to their senses and beg your forgiveness, you may allow yourself to be mollified.)
