They can determine race from handwriting? Anyone in Freeperdom a graphologist?
Not from handwriting, or not just handwritting, but from grammer and maybe spelling.. Native speakers of languages other than English tend to make grammatical errors that wouldn't be errors in their native languages. Spanish speakers for example have a lot of problems with his and hers, since there is no equivalent in Spanish, although there is a "theirs", and a singular non-gendered "su" for his/hers, our exchange students ususally used "his" even when the object referred to belonged to a female. German speakers sometimes use a particular word order, like "I am to the store going", and so forth. Even the children of non native speakers, even if their first language is English, sometimes make the same mistakes, and this effect can last for several generations in areas when the mixing bowl doesn't apply. I've heard plenty of central Texans and people from other places with "German" accents and word order, even though they are 4th or 5th generation.
