Yeah, if we'd tried treating my son's MRSA pneumonia with vitamin C and grapefruit seed extract, we would no longer have a son. And he doesn't have recurrent staph, either. The antibiotics killed the infection and it never came back. Making blanket pronouncements like, "You will get a relapse," or "Antibiotics destroy the immune system" just weakens your argument and makes you look uninformed, IMHO. My son had one of the most powerful antibiotics known to mankind and yet still amazingly is able to recover from colds just like any other kid, so clearly his immune system is in a non-destroyed state.
Partially because I had a child almost killed by antibiotic-resistant bacteria, I am a huge proponent of avoiding antibiotics whenever possible. I think that antibiotic overusage is a huge problem in our society. But there are some problems for which they are needed, and denying that is just silly. Again, IMHO.
