So, basically, here we have a verdict dilemma. Mandelstam converted out, but basically did it so he can go to college, and didn't practice Christianity. Usually, when people convert out, "Borderline" is as high as we go -- and for modern conversions, "Barely". But since this can be considered a forced conversion, definitely without any religious undertones, we'll go with "Jew" here. It's our website, after all.
