I can suggest 2 reasons. One is that it is Christmastime, so a lot of the Christians will be busy making traditional Christmas preparations. The other is that the atheists that choose to come to a religious forum will tend to be people looking for an argument.
Actually there could also be a third reason, to do with the types of question you are asking. But I have not analysed your questions to form any hypothesis about that, because, er, it’s Christmastime and I have been busy writing cards, practising carols, decorating the tree, wrapping presents and making arrangements for Christmas Day.
