Names and some identifying circumstances changed to avoid lashon hara.
One of the skills my wife and I teach in our mentoring of BTs and converts is how to ask a rabbi a question. Here's an excellent example of how not to do so, based on a real life experience.
A pre-convert had been told by his rabbi to read the kitzur shulchan aruch (a big mistake, IMHO, but that is another essay) and when he was done come back and they'd talk about it. In one of the sections on Shabbat he came across a section that claimed it was forbidden to violate Shabbat in order to save the life of a non-Jew, unless failing to do so would arouse hatred against Jews. Of course, this is a legal loophole - at least until Messiah comes it will always be the case that failing to do so would arouse hatred against Jews.
Anyway, our pre-convert was upset by this. He was understandably unhappy with the notion that he might be obligated to stand by and watch his birth parents die if the only way to save them was to violate shabbat. He went to his rabbi on Friday night, immediately after services, and when his turn came to shake the Rabbi's hand and wish him good Shabbas, he asked 'Do people really follow everything that is in the Kitzur?' The Rabbi, mindful of the long line of people waiting, his wife and dinner waiting for him at home, and the sheer vagueness of the question, replied 'Of course they do'.
Undoubtedly a small amount of the fault for the wrong information conveyed in this story falls to the Rabbi. But much more falls to the questioner. He asked the wrong question, in the wrong circumstances, and then did not follow up when the answer seemed to make no sense.
