Not true at all, but I am willing to bet that it exists just as this person states in the vast majority of schools around the country. If you are from soutern areas of Va. then it is still conservative down there, but NoVa is very different. I grew up in Annandale, and now I hardly recgonize the place when I go back to visit, so I don’t anymore.
I’m not sure what you are claiming is not true at all, but I have no doubt it exists in the district where the writer lives.
I live on the Eastern Shore, not southern VA, but we are far different here from NoVA, although there is much influence from there.
