> I honestly don't feel like anyone feels like the water is heating up slowly.
that is the entire point of the metaphor/idiom/parable - you do not feel anything - until it's too late - you're dead or in jail or homeless or deported.
No, my point is that everyone feels the water being too hot already because it has happened quickly, not that nobody has noticed it heating up because it has happened too slowly.
It's more like draining the water in the pot and pouring in already-boiling water, than it is like heating it up slowly.
