Pretending rising sea levels are only recurrent flooding does not make it so.
Euphemisms usually fail in politics. The public is smart enough to see through the trick when advocates rename something to make it more palatable. Pro-life is still anti-choice. Revenue enhancers are still new taxes. Regulatory easing is still lifting environmental and workplace protections.
Politicos play the game anyway, and occasionally a linguistic back flip helps legislation pass. Consider a case from the General Assembly this year.
