We're way deep into a thread now, but it's an important problem. I would very seriously argue that someone who does not write clearly in their native language has not reasoned clearly enough about what they are trying to express. They may experience, feel, believe, express, or desire, but without the language, they have not reasoned about it with clarity. What's more, they are relying on something other than reason to prevail. It's analogous to the "you only know something as well as you can teach it," or Feynman's "explain it to a child," learning technique. Regarding the apostrophe, it's a fine catch and I would ask whether the effort the writer made was commensurate with their intended purpose.
