You can see this happening in the Stanford list itself - some of the terms listed, particularly in the "Ableist" section, are clearly second or third iteration through the euphemism treadmill.

In fact, some could be about to complete another one - for example, my self-preservation instinct on the Internet tells me I shouldn't use "disabled" as an adjective, despite it being listed as a proper alternative to "crippled". I fully expect "disabled" to land in the left column of this or similar list in a couple of years.
