Many Haredim, especially Hassidim, become aggressive amongst eachother in shuls over petty matters after 3 days of no or poor sex, too much food and sugar, no exercise, uninspiring davening, poor rebbe and rabbinic leadership, no Amolekites to shecht, no 3rd Temple to build, a feeling of distance from Hashem: "The problem is that there's just too much food: it's just too good!" (R.Avigdor Miller)
