Health (and, agav, PBA)- Guess what? Some of us aren’t American. I know it may seem strange to you but many people don’t actually live in America – why should we assume that my abbreviation stands for your American profanity? We haven’t heard of it just as much as you haven’t heard of our abbreviation. That’s why the mods don’t assume that people reading would think it means yours anymore than ours. They, unlike you, can appreciate the fact that Americans are but a minority of the population of planet Earth, and Americanisms but a minority of colloquialisms within the English language.
Having said that, had I known before I posted that your version existed then I wouldn’t have used the abbreviation knowing that Americans may not be aware of the English usage as opposed to the American one.
