From that BBC article today:
In 2019, the cities of Kortrijk and Dendermonde renamed their Leopold II streets, with Kortrijk council describing the king as a "mass murderer".
And in 2018, Brussels named a public square in honour of Patrice Lumumba, a hero of African independence movements and the first prime minister of Congo, since renamed the Democratic Republic of Congo.
Last year a UN working group called on Belgium to apologise for atrocities committed during the colonial era.
Charles Michel, prime minister at the time, declined. He did however apologise for the kidnapping of thousands of mixed-race children, known as métis, from Burundi, DR Congo and Rwanda in the 1940s and 1950s. Around 20,000 children born to Belgian settlers and local women were forcibly taken to Belgium to be fostered.
Some people may not care, but others won't stop until something gets accomplished. And some people on both sides apparently do care.
