So, yes, let’s take the figure of the feminist killjoy seriously. Does the feminist kill other people’s joy by pointing out moments of sexism? Or does she expose the bad feelings that get hidden, displaced, or negated under public signs of joy? Does bad feeling enter the room when somebody expresses anger about things, or could anger be the moment when the bad feelings that circulate through objects get brought to the surface in a certain way? The feminist subject “in the room” hence “brings others down” not only by talking about unhappy topics such as sexism but by exposing how happiness is sustained by erasing the signs of not getting along. Feminists do kill joy in a certain sense: they disturb the very fantasy that happiness can be found in certain places. To kill a fantasy can still kill a feeling. It is not just that feminists might not be happily affected by what is supposed to cause happiness, but our failure to be happy is read as sabotaging the happiness of others.
