I think you're agreeing with me in that term logic is inappropriate for rigorous uses, though your examples are not really the results of its admitted flaws. Let me clarify the area where I believe it is useful: the study of term logic helps prepare the minds of non-philosophers to reason, speak, and write clearly about concrete but often ill-defined matters of everyday life. While it lacks rigor, it forces them to consider the implications of their words and those of others, and how those words operate to express proof and disproof. The study of symbolic and other more formal systems of logic, while essential for more rigorous reasoning, requires too much time and application to achieve similar results, because their mode of expression is too removed from the experience of non-philosophers and especially non-mathematicians.
