Milan Kundera said this quote

“ The method of addition is quite charming if it involves adding to the self such things as a cat, a dog, roast pork, love of the sea or of cold showers. But the matter becomes less idyllic if a person decides to add love for communism, for the homeland, for Mussolini, for Roman Catholicism or atheism, for fascism or anti-fascism. In both cases the method remains exactly the same: a person stubbornly defending the superiority of cats over other animals is doing basically the same thing as one who maintains that Mussolini was the sole saviour of Italy: he is proud of this attribute of the self and he tries to make this attribute (a cat or Mussolini) acknowledged and loved by everyone.Here is that strange paradox to which all people cultivating the self by way of the addition method are subject: they use addition in order to create a unique, inimitable self, yet because they automatically become propagandists for the added attributes, they are actually doing everything in their power to make as many others as possible similar to themselves; as a result, their uniqueness (so painfully gained) quickly begins to disappear. ”
