Yes, really. I am not saying that volatility (again, by my personal definition, which I don't claim is universal) there was no volatility before, but rather that I see an inflection point around 2015. For example, I don't think there were ever polls asking whether President Bush should have been impeached, but if there had been, the level of support for it would have been tiny, despite all the things you listed. On the other hand, a majority or near majority of people polled regularly supported impeaching the current president. There are other examples in other countries. But again, I really don't think we have an objective standard to measure against, this is just what I see.
