The Kelvingrove Museum in Glasgow has exactly the right approach to confronting racism, slavery, colonialism, etc, in its exhibits. Does looking at it, its effects on real people, and impact on history, society, religion, and culture make you uncomfortable? Good. It's fucking supposed to.
When I was in Berlin in 2016 there was an exhibit of German colonialism. The first room was the genocide of Herero and Nama peoples and last on how the rhetoric and race-"science" that was invented to support colonialism are still with us to day. One of the best museum exhibits I've ever been to.
This reminds me of visiting the Topography of Terror in Germany. The site is heavy, emotional , and one that makes you understand the importance of remembering history, and confronting it. Kelvingrove appears to follow in a similar vein and it is an important message. www.topographie.de/en/
