One problem with such disprovings is that they don't get into the actual case of what's happening, just stay on what people say.
People could say the same thing for 200 years, but they might not say it at the same numbers or with the same intensity over those 200 years - and of course even if those were stable, the thing might or might not be actually happening during some of those years.
As an example (not making a X-to-Nazi comparison, so Godwin has no power here): People have been complaining about fascism from 1920 all the way to 2023. But there are still periods with hugely more actual fascism, say 1993-1945.
