Black Lives Matter

Black Lives Matter appears in sp.05 【刘擎x林垚】"枪杀医保巨头"案背后的思考（下）：分裂的美国会有宪政危机吗？ as a social movement whose public support rose after 2020 and later declined. [[LiuQing|刘擎]] cites Pew Research Center polling, while [[LinYao|林垚]] cautions that short-term approval curves do not settle a movement’s historical effect.

The source compares BLM’s trajectory to older civil-rights movements whose legitimacy changed over time. It also notes that many police-reform demands became blocked locally or sorted by party, making BLM part of the source’s larger Identity Politics As Political Sorting and American Democratic Resilience branch.
