These terms don't bother me. To me, they're a way of reminding those of us who feel blessed to be a blessing to someone else, even in the smallest way. (Because what's small and insignificant to one, can be huge to someone else.)
Now there are certain current buzz terms which are quite prevalent right now, especially among campaigning politicians and ivory tower academicians. I won't mention them, because this isn't a board for political debate. However, when I hear those terms, I close my ears, so I certainly understand where you're coming from.
