Verticality, hierarchy, quality and similar are thrown out for the sake of flattening all particulars and individual phenomena into the same plane of "goodness" or "validity". "Everything goes" can only be true if there are no qualities at all, but if you so much as admit superiority of one thing (normalcy) over another (distortion), then from there necessarily proceed the support and promotion of normalcy, and suppression of its opposite; "tolerance" must go only so far as to give some "breathing space" and time to troubled individuals to reconsider their behaviour, not to tacitly accept their excesses as "not that bad".
