"[5] Aldridge serves as director of the organization "Young Activists United St. Louis" and sits as student co-chair on the non-profit organisation "Missouri Jobs with Justice".

He was appointed on the Ferguson Commission, created by the State of Missouri following the shooting of Michael Brown in August 2014 in Ferguson, Missouri and the subsequent civil unrest, whose mandate was to submit policy recommendations in various areas of social life, such as citizen-law enforcement interaction and relations; racial and ethnic relations; municipal government organization and the municipal court system; and disparities in areas including education, economic opportunity, housing, transportation, health care, child care, business ownership, and family and community stability.

[11] On January 30, 2020, he introduced, along with co-sponsors Bob Burns and Chris Carter, of Districts 93 and 76 respectively, House Bill 2352 that would designate April as "Limb-Loss Awareness Month" in Missouri.

[12] On June 28, 2020, Black Lives Matter protesters entered Portland and Westmoreland Places, a private gated community, to protest at the residence of St. Louis Mayor Lyda Krewson, and demand her resignation, on the grounds that she had publicly read names and addresses of those who had submitted letters calling to defund the St. Louis Metropolitan Police Department.

When asked about the group marching on private property, Aldridge responded, "Just like in many disobedient protests, even in the '60s, you break laws, make people feel uncomfortable [but] we're not doing anything where we're hurting anyone or putting anyone in danger.
