I have no sentimental feelings for the Confederacy. I believe slavery was an abomination. The country paid a staggering price to preserve the Union and get rid of slavery (and the South paid most of all), and it was all worth it.
I have never owned or displayed any Confederate images or memorabilia. It doesn't appeal to me, and I try to avoid offending others on general principle.
And yet, if this design is capable of giving so many progressives hissy fits, it must have something going for it.
