That's one ridiculous exaggeration. Did you even read the law you are talking about, or you are just repeating somebody else's propaganda? The law was actually criticized by Ukrainian minorities -- by Crimean Tatars [1], by Association of Jewish Organizations and Communities of Ukraine[2], by Congress of Ethnic Communities of Ukraine [3]. But the most important detail -- the law in fact wasn't repealed! Acting president already vetoed its repeal.
