Tarnished by the progressives themselves.
Speaking of "verbal jiu-jitsu" look at how "family values" became a pejorative, derrogatory term, or how only conservatives can be "culture warriors" or how the story is never the bad things Democrats do or the wrong things them say, but "Republicans pounce/seize/weaponize." SDI became "Star Wars." Supply-side economics became "Trickle Down" and then "Trickle On." Rather than being an experimental method of finding the truth, " The Science" came to mean whatever bureaucrats told us to believe. Consider, too all the ju-jitsu involved when liberals want to avoid saying "illegal immigrants."
Moreover, it wasn't like liberals invented words like "diversity" and "inclusion" and "equity." They appropriated them and attached them to their policies, hoping that the good sound those words had would make people favorable to their policies. When people see what DEI or CRT really means, of course they have negative reactions. To expect otherwise is to demand people surrender their freedom of thought.
The proper term is “illegal alien”, not “illegal immigrant”.
Like “Far Right” (I’ve been called that), versus the apparently non-existent “Far Left”.
