The short answer to your question, Eric, is that Jews believe that the name of G-d should not be written down in full, even in languages other than Hebrew, except in the context of praying. Where it is written in full, the paper on which it is written is treated with extraordinary respect, and damaged or old prayerbooks are never thrown away but actually interred. This all stems from a belief that words and language are extremely important, and none more so than G-d's name. Incidentally, many Jews will also not pronounce G-d's name, including in English, but will use one of a series of nom-de-plumes instead, including "HaShem" (the Name), "haKadosh barukh Hu" (the Holy One, blessed be He), "Ribono shel Olam" (Master of the Universe) and many others. Judaism uses a lot of abbreviations, and this is sometimes done for the English version of these names when they're written, eg HKBH for haKadosh barukh Hu.

Your statement was well-written, polite and not an iota offensive to anyone.
