“The worst form of inequality is to try to make unequal things equal.”
Whilst a paraphrase this is based off of Aristotle's writings as Aristotle stated "For instance, it is thought that justice is equality, and so it is, though not for everybody but only for those who are equals; and it is thought that inequality is just, for so indeed it is, though not for everybody, but for those who are unequal" in https://www.loebclassics.com/view/aristotle-politics/1932/pb_LCL264.211.xml Politics, III. V. 8.

"Den Gleichen Gleiches, den Ungleichen Ungleiches - das wäre die wahre Rede der Gerechtigkeit: und, was daraus folgt, Ungleiches niemals gleich machen."
