An identity conflict

Explanation:

Self-Concept

This is simply known as the way a people sees, understands, and defines themselves.

Social identity

This simply deals with the social aspects of the human self, that is, it is the part of ourselves we use to create an impression, to let other people know who we are and what can be expected from us. Identity often refers most times to aspects of the self that are socially observable or publicly available outward, such as ethnicity or gender or age.

This kind of crisis do happens if an individual is forced to make an important and difficult life decision. They uses the "approach-approach" conflicts method in that the person wants to reach two mutually contradictory goals.

Even though these conflicts involve wanting two desirable identities, identity conflicts uses intense feelings of guilt or remorse over perceived unfaithfulness to an important aspect of the person's identity.

Explain how the quotation below illustrates the philosophy of the Civil Rights Movement. Your response should be a minimum of three sentences in length.

Answers

Answer: This quotation helps to illustrate the Civil Rights Movement, because as Martin Luther King Jr. said, “an unjust law is no law at all.” This means that he is suggesting that we should not obey unjust laws, and that we all have a responsibility to do so. Since people of color are treated much more differently than whites, that is known as an unjust law. An example of a just law would be both blacks and whites being treated equally. He recommended everyone to obey just laws because they would help bring equality and justice in the future.
