English is classified as a Germanic language by linguists not because of any real properties of English-as-she-is-spoke now but because of its genetic heritage. It's a little more subjective, but I also kind of disagree with the rest of your comment. Uncleftish Beholding uses Germanic vocabulary but the grammar and structure is modern English, so the fact that it's possible doesn't reflect anything, one way or another, on whether "the way thoughts are stacked up and laid out" in modern English is Germanic or Latinate. Broadly, the way thoughts are stacked up and laid out is pretty similar in either family (compared to, say, Japanese), but if anything modern English resembles French in this aspect just as much as it resembles German, notably in how English and French have both become mostly analytic, whereas German has remained comparatively synthetic. The reason Uncleftish Beholding is possible whereas a Latinate version isn't is simply because commonplace grammatical words (articles and the like) remained Germanic in English, even when there were similar enough equivalents in French. But, again, the origin of a language's commonplace grammatical words don't determine a language's classification - genetics do.
