He is saying to not judge a person before knowing them properly. To understand the perpectives of people that face things like discrimination and not to have bad opinions on them.
Robert Menzies was in office twice, from 1939 to 1941 and from 1949 to 1966. Despite seven successive federal election victories, Menzies’ second period as Prime Minister was not secure. In the 1954 and 1961 federal elections, the Labor Party received a greater proportion of first preference votes for House of Representatives seats (50.03 per cent in 1954) than the Liberal and Country parties combined. Menzies was fortunate to come to office in a growing postwar economy. He also benefited from the Labor split in 1955, and skilfully exploited ‘Cold War’ fears and the threat of Communism for electoral gain.
