a hashtag to campaign against racism and police brutality against African Americans in the United States. The movement contributed to a revitalization and re-examining of the Black feminist movement. While the deaths of Black men played a major part in the Black Lives Matter movement, Rekia Boyd, Michelle Cusseaux, Tanisha Anderson, Shelly Frey, Yvette Smith, Eleanor Bumpurs, Sandra Bland, and other women were also killed or assaulted by police officers. While Black Lives Matter has been critiqued for a failure to focus on Black women's treatment by the police, it has since been better about incorporating the interlocking systems of oppression that disadvantage Black women in particular. Activism of Black feminists in Black Lives Matter has included protests against political candidates such as Bernie Sanders, Donald Trump, and Hillary Clinton, and they have used hashtags such as #oscarssowhite and #sayhername. Black feminist identity politics and safe spaces Black feminist identity politics can be defined as knowing and understanding one's own identity while taking into consideration both personal experience as well as the experiences of those in history to help form a group of like-minded individuals who seek change in the political framework of society. It also can be defined as a rejection of oppressive measures taken against one's group, especially in terms of political injustice. Black feminist writer Patricia Hill Collins believes that this "outsider within" seclusion suffered by Black women was created through the domestic sphere, where Black women were considered separate from the perceived White elite who claimed their dominance over them. They also felt a disconnect between the Black men's suffering and oppression. As a result of White feminists excluding Black women from their discourse, Black feminists expressed their own experiences of marginalization and empowered Black consciousness in society.

Ignoring these differences only creates more of a divide between social movements and other feminist groups, especially in the case of violence against women
