The node was a "place=hamlet" which is quite small compared to a state and quite some experienced mappers already touched it without deleting it. So in my experience it is you who should give a (very) good reason why it shouldn't be here.
If you're unsure you can always ask first. A good place would be the US OSM slack or the community at c.osm.org

So: Why do you believe there isn't a small dwelling called Kansas in this place?
