When we say race is a social construct, its relating to the fact that there are no inherent biological differences between humans, instead it is a social and cultural notion that we hold that typically holds no real meaning. Due to this, it has led to racial stereotyping, and racial discrimination.
Throughout American history, the idea of race has resulted in systemic oppression and discrimination against specific racial groups. For example, African Americans endured constant racial discrimination as well as slavery and segregation all throughout American history.
Other minority groups, including Native Americans and Asian Americans, have also been impacted by racial discrimination. In February 1942, President Roosevelt, as commander-in-chief, issued Executive Order 9066 that resulted in the internment of Japanese Americans.
These discriminatory behaviors have led to unequal access to resources, opportunities, and basic liberties.
