The problem is that people, like you

, have invented their own definition of herd immunity which is different than the way Infectious Disease people use herd immunity. The proof of real herd immunity won't come from case dropoff. It will come from from how many and the size of future outbreaks. Not that exiting this phase isn't an important milestone, so I am not diminishing the importance of it. But regular people and ID people are side-tracking this, and regular people are using it to say experts are misinforming us, or outright lying or wrong. If this becomes endemic, like cold & flu, we will only have partial herd immunity, not full. For regular people, it will be "good enough." But ID people would still be correct when they say we don't have full herd immunity and mention the higher 80, 90% numbers or if ever.
