Whilst i understand the emotion and reasons behind these statues being pulled down by mobs, I am also concerned about the systematic eradication of the past.
The way I see it, these artefacts are a powerful reminder of atrocities that have happened, and a stimulus for really rich debate, much like we're seeing here. I agree that it was not widely known who Colston was until this week, and what's happened to the statue has played an important role in this. It's not the objects themselves that are problematic but the context in which they exist. Until this week, Colston has stood on a plinth to be venerated much as the day the statue was installed. Much like Auschwitz has been preserved (imperfectly) as an important reminder of what mankind is capable of, these statues have a power too that can be put to great use. I personally find it chilling, and moving, to reflect on the faces of these individuals and the actions they have felt justified in taking. It's valuable to 'put a face' to the perpetration of slavery instead of making it an abstract concept or something that 'happened' to people rather than something that was enacted upon them by others. It can tell us a lot about society now and in relation to how things have been in the past. We all have the capacity to turn a blind eye, or even to do terrible things, and it's valuable to have the stimulus to reflect on that in a personal way.
I'm not sure it's a question of whether they stay or whether they should be removed. Neither seems to have much power to me. However, the context in which they're experienced could be radically examined to make people think deeply about the slave trade. This could be about juxtaposing them against commemorations to the victims of the slave trade. The Bristol response (tiny contextual plaque) was woefully inadequate and I can see why there's so much anger around this. It does feel like a bit of an apologist response.
Rather than destroy these statues or hide them away, it could be really powerful to use the fourth plinth in Trafalgar Square alongside displays about the horrors and legacy of slavery to actually educate people and get them talking. My fear about iconoclasm and just removing things is that it sweeps it under the carpet and makes it easy to forget, when actually these statues can be used to move things forwards.
Sorry, this is a really clumsily written post! Basically my view is they shouldn't be left to be venerated in their original context, but I don't think they should be destroyed / hidden from view forever more either. But then I am an historian rather than someone who's suffered as a result of slavery's legacy so I can't really comment on the pain of being exposed to them day in day out either.
