@Luis Gonzalez Yet another superior, well-reasoned and useful piece. Thank you.
In exploring a specific category of linguistic manipulation - patriotism vs. nationalism - you have done much more than expose how journalists and politicians alike subvert language to promote a preferred narrative.
We already knew that.
Of more value, what you have accomplished is to explain the technique by which target audiences are subtly led to draw a preferred conclusion, often without making a conscious choice.
Such linguistic legerdemain is akin to a magician's art: it involves careful framing, misdirection, and substitution.
And by and large: it works. Unless you know what to look for.
Keep up the great work.
