How is this "history repeating itself"? A few people objected during the Spanish flu so if we have even a single person that objects nowadays it's "history repeating itself"? What if we discriminate against a minority based on their belief (e.g. refusing a medical intervention) and don't allow them to live a normal life. Is that also history repeating itself? I can think of a few instances in history where groups were prosecuted for their convictions. Are we currently repeating that part of history?
