When I was in college, one freshman put the Confederate flag in his window. It was fairly prominent: I would pass it every day. I never knowingly met the guy.
I grew up in the Northeast and this struck me as seriously weird. Ditto for another NE friend of mine. We figured some Southerners were living in the past. But mostly we were baffled. Why revere a rebellion dedicated to keeping slavery and possibly low tariffs on manufactured goods? (Today I buy the latter even less: I had an AP knowledge of US history at the time.)
Another friend from Virginia told me that the guy was actually from upstate New York. Wow. Even weirder. When I asked why, I was told that the guy thought it was cool. So yeah, I accept LHoD’s categories, until somebody makes a convincing argument otherwise. This seems to be a case of an ignorant idiot.
It was also explained to me that among some, displaying the Confederate flag was a way of showing solidarity with the Klan. Oh. Didn’t know that.
The flag remained in place in this northeastern college for 2 consecutive semesters, after which the guy moved elsewhere. I don’t recall anger or outrage. Personally, I was pretty quizzical.
