HorseGirl is a nice enough gal, and on other subjects, quite reasonable. I know - I've had literally thousands of interactions with her over a period of several years.
I can dispell the notion she is a White Supremacist, she's not. She even leans liberal on most things.
She is however, thoroughly tied to her granddaddy's view of the Confederacy in a rather childlike innocence that has remained with her. Nothing, and I do mean - nothing - you can say will dissuade her of the fables she was told as a child, which she believes to be absolute truth.
What she gleans from 99% is what she heard gpapa - in an Confederate Old Age home -- from an over 100 year old rebel in the 1930's heard, and her being told this late in his life i(n the 1990's, as I recall).
In fact, I even looked up the Soldier History of the rebel vet her gpapa told her about, and presented her with the details of him being thrown in a Union prison for most of the war (yeah, that couldn't have had any effect....)
The other 1% comes from the (completely debunked) Kennedy Twins "The South Was Right."
She will not look at any information presented outside of those sources. No matter what/
Trust me on this. Believe me, I've tried. Beyond that, she's a genuinely nice gal.
