"We did it to ourselves"

In a 2010 piece for Alternative Right, Australian writer R.J. Stove
laments the suicide - demographic and cultural - of WASP (White Anglo-Saxon Protestant) Australia.

Stove:

... if we Australian WASPs (and I, though Catholic by choice, am largely WASP by ancestry) have become strangers in our own home, it is fruitless to go around blaming Jewish behavior. We did it to ourselves. (With substantial help, admittedly, from bellyaching Irish ex-Catholics, not to mention from Calabrian Mafia thugs.) Our position, and ultimate complicity in our own doom, may call to mind the 17th-century Spanish proverb: “Castile has made Spain, and Castile has destroyed it.” For “Spain” read “Australia,” and for “Castile” read “the WASP”.
