you should never ask anything to fuck off. because it is a powerless act. and it makes both you and the overall community look underaged.
trying to attack somebody's desire to belong and fit-in is not what grown-ups do. (nor does it have any power over them whatsoever) it is what little children do. getting angry and emotional in such a way that has zero actual power is not what rational adults do. it is what children and women do. it is a tantrum and nothing more. fuck-off posters are an embarrassment to this or any community that pretends to be composed of adults.
