Problem: Black people:

By that time, the majority of black people in the United States were native-born, so the use of the term "African" became problematic. Though initially a source of pride, many blacks feared that the use of African as an identity would be a hindrance to their fight for full citizenship in the US. They also felt that it would give ammunition to those who were advocating repatriating black people back to Africa. In 1835, black leaders called upon Black Americans to remove the title of "African" from their institutions and replace it with "Negro" or "Colored American". A few institutions chose to keep their historic names, such as the African Methodist Episcopal Church. African Americans popularly used the terms "Negro" or "colored" for themselves until the late 1960s.

Problem: Labour Party (UK):

Labour went on to win the 1950 general election, but with a much reduced majority of five seats. Soon afterwards, defence became a divisive issue within the party, especially defence spending (which reached a peak of 14% of GDP in 1951 during the Korean War), straining public finances and forcing savings elsewhere. The Chancellor of the Exchequer, Hugh Gaitskell, introduced charges for NHS dentures and spectacles, causing Bevan, along with Harold Wilson (then President of the Board of Trade), to resign over the dilution of the principle of free treatment on which the NHS had been established.
