Answer:
The correct answer is D, <em>Only the Red Scare was about communists, but both became violent</em>.
Explanation:
Red Summer is how it's called a series of mob violence that happened in 1919 soon after World War I (1914-1918) American veterans got back from war. American forces had thousands of black men that when returning did not accept segregation passively anymore, assuming they ever did.
Even before renewed resistance from black men started, racist white people had already realized that after fighting for America black people wouldn't accept racism naturally as they supposedly had done before. These people understood that after military service black men would demand to be fully treated as American citizens, threatening racial subordination.
This led to physical violence caused by white mobs in many parts of the country. In Elaine, Arkansas there was a massacre where over 200 hundred black people were killed, and throughout the country around 97 black men were lynched. Black veterans reacted and defended themselves since the public power ignored what was happening: they formed groups to protect their communities and houses.
Red Scare is the period in late 40s and early 50s whose most memorable events were Republican Senator Joseph McCarthy's use of anticommunism to politically promote himself. By taking advantage of the Cold War and widespread fear of communism he got to realize public hearings to find communists in the government.
Because of this systematic political persecution hundreds of people lost their jobs and civil and political liberties were violated.
