Believe me, being a Christian, Sarah should be the least of anyones worries except marxists who are trying to change the very core of our values and our constitution. No, my friend, much less to worry about with Sarah.
The problem lies with the fact that many Christians are unaware of the history of forced conversions, Jews being burned at the stake, forced ghettos outside the vatican etc. There is a long history of this behavior. This country is very young, it does not share most of that guilt. But remember, many Jews here are either first or second generation Americans. They still feel that fear. It makes them hypersensitive and afraid. I always try to take that into consideration. I’ve seen Russian Jews who are new arrivals here stand in Shul and cry with wonder over the fact that they are now free to practice their faith.
