I agree that language is important for effective communication. I also am cognizant of how language changes over time, in meaning, connotation, usage, morphology. One can find problematic usage in a lot of places if one chooses to look. I don't believe that's what you're doing here, and don't mean to put forth some reductio ad absurdum argument. I'm interested to learn what heuristic you use to decide what language is acceptable and what needs to be changed. Would you mind sharing?
