Philistinism

In the context of recent events and controversies, it seems difficult to ascribe good will to the posting of this.

Not that this derogatory usage would have looked good a few years ago. The roots of the word seem to be here -

- so, basically a "Greek immigrant group from the Aegean that settled in Canaan circa 1175 BC [...] they gradually assimilated elements of the indigenous Levantine Semitic societies while preserving their own unique culture. In 604 BC, the Philistine polity, after having already been subjugated for centuries by the Neo-Assyrian Empire (911–605 BC), was finally destroyed by King Nebuchadnezzar II."

Using the name of an ethnic group as a derogatory slur, after they've been wiped out by the (arguably) most powerful empire of their historical age, strikes me as a fairly despicable behavior.
