Historically marginalized groups play a crucial role in influencing policy reform through advocacy and activism. Organized movements, such as those fighting for civil rights or gender equality, can bring attention to systemic injustices and mobilize public opinion. These groups often engage in lobbying and grassroots campaigns that challenge existing policies, highlighting the need for inclusive reforms. Their involvement is essential for shifting sociopolitical narratives and ensuring that the needs and voices of all populations are considered. This active engagement can lead to meaningful and lasting policy changes.
