[3] He founded and was chairman of the not-for-profit Christian Anti-Communism Crusade (CACC), based originally in Sydney and later in Long Beach, California.

During his time with the CACC, Schwarz gave lectures and seminars across the United States on the subject of communism, placing an emphasis on the role of education in understanding Marxism-Leninism from that movement's source documents by Karl Marx, Vladimir Lenin, Leon Trotsky, Mao Zedong, and others.

[5] Schwarz organized a "Southern California School of Anti-Communism" that filled the 16,000-seat Los Angeles Memorial Sports Arena from 28 August to 1 September 1961.

The foreword reproduces a letter in which US President Ronald Reagan, with whom Schwarz had been friendly for many years, wrote (on 4 January 1990): "Fred, you're to be commended for your tireless dedication in trying to ensure the protection of freedom and human rights."

In his 50 years of work in the United States, he trained a whole generation to recognize the evil and the danger of Communism at home and abroad.

In Schwarz's obituary Derek H. Meyers wrote, "Although this industrial action seemed scandalous to older doctors at the time, it is clear that every graduate of an Australian medical school since then owes a debt of gratitude to Fred."
