You have to remember that the "thunderbolt cross" is a symbol that has been used thousands of years by multiple cultures, long before its perversion by the Nazis. It is still widely used as religious symbol in Hinduism, Buddhism and Jainism. Jews should not be, and generally aren't, offended by swastikas in Hindu and Buddhist temples, because there are absolutely no anti-Semitic connotations. All the more so, should we not take offense to architectural oversight.
