It's not a fact at all. Soros took refuge with a tax collector who was hiding his own jewish wife. The thirteen year-old Soros was never a "collaborator" who "ratted out fellow jews". This is a stupid story Alex Jones buttgoys tell so they can put a kink in the libertarian-to-nazi pipeline and pretend that jews like Soros, whose observed behavior is exactly that which incited hatred of jews in the 20th century, are somehow "nazis" and should be opposed on that basis. The CBS interview that is cited, mendaciously, as the source for this lie, directly refutes it. Soros is a liberal. What Soros buys with his money, acquired through speculation on currencies, is "Democratic" "Open Societies", which is what FDR and his Progressive movement sought. The opposite of the political conditions Soros buys with his money is a closed society which defers to the needs and culture of its native citizenry, and this is what Soros' shills call "nazis" because it is what the NSDAP wanted for Germany.
