Compared to Belgium, the UK is very open about its Colonial past. You might find this interesting - I posted it on another thread the other day.

I moved back from near Tervuren last year, and there were moves afoot to take back artefacts from the Africa Museum, and several articles debating this in the local press. I think, from what I gleaned, it isn't something the average Belgian thinks about. The Colonial Palace is used for balls, dinner dances, conferences, dinners, meetings etc, and no eyebrows are raised at the name. In one of the villages nearby is a bar called In Den Congo (In The Congo), which is a normal bar, but the name always seemed a tad dubious to me.
Statues; it's a BLM website that is calling for some statues to be taken down. If you want acknowledgement of the UK's colonial past, then keeping the statues up will achieve that, as contextual information can be put by the statue. Does the fact that Guy founded, endowed and used his ill gotten gains to ensure that the poorest of the poor had access to hospital care negate his actions in the first place? I don't know - but the hospital is still there. Do we only remember the bad people have done? Can we have second order good from first order evil as with Guy? People were and are now, multi faceted. I'm not sure we can judge the actions of an individual in past times by the mores of today, without taking into account the time they lived in, and the societal pressures, laws and beliefs of the time.
My Mum feels very strongly about the statue in her small town that is on the list; many service veterans feel very strongly about the Cenotaph and other war memorials, especially the last of the WWII generation, given we've just had the 76th anniversary of D Day last weekend; it was the 75th anniversary of VE day not so long back, and VJ day is on August 15th. The latter is especially poignant, given the awful treatment of POWs on the Burma railway.
Slavery and colonialism are still happening today. I wonder what the verdict will be on the Chinese colonisation of the African continent that is happening now?
