Final answer:
President Biden has made contributions to advance critical race and gender theory through policy proposals and actions. These include issuing special equity grants, supporting same-sex marriage rights, and appointing a diverse cabinet member.
Step-by-step explanation:
President Biden has made contributions to advance critical race and gender theory through various actions and policy proposals. For example, one of his contributions is the proposal of issuing special equity grants to Black Americans and other racial minorities in certain sectors, such as farming, to compensate for past discrimination in public services. This is aimed at achieving a fairer and more equitable society.
Another contribution is Biden's support for same-sex marriage rights. His views on same-sex marriage evolved over time, and he publicly voiced his support for the rights of same-sex couples to marry. This had a significant impact on the country's perspective on marriage equality.
Furthermore, his appointment of Pete Buttigieg as Secretary of Transportation, making Buttigieg the first openly gay cabinet member in US history, is another contribution to advance critical gender theory. This appointment demonstrates Biden's commitment to promoting diversity and inclusion in his administration.
