The Colston statue went up in 1895 and slavery was already many years illegal and viewed as an abomination by nearly all. The statue and all the "Colston Day" events and personality cult were invented by upper class citizens of Bristol who believed the city needed a kind of moral idol to personify the city. The statue itself and the cult surrounding it were actually truly trying to re-write history as myth. The Bristol Merchant Venturer's Society are the last remnants of that cult with any real influence in the city and confounded attempts for years for any contextualisation around a statue glorifying one of the biggest slavers in British history smack bang in the middle of a city with double the national average of black residents. Old Eddie ending up in the drink is the inevitable end-point of people being ignored for at least three decades of trying to find a way to resolve it amicably.Gandhi also didn't like Africans at one point in his life making a string of racist comments about them.
To me it's always difficult to apply modern standards to historical events/ and characters. It's not that we shouldn't do it and be in a position to not have an opinion or not pass moral judgement or even shake things off entire as "that's how it was in those days". But we nevertheless need to apply quite a few caveats at the very least with respect to how those times where, what the 'sciences' of the day said and how things were frankly more tribal and less globalised.
Colston was a beast made filthy rich by trading humans and even his famous "philanthropy" was explicitly only made available to institutions of his own denomination of Christianity. As Tory MP for Bristol he fought tooth and nail against the abolition of slavery and he was unrepentant, even as slavery was steadily becoming to be viewed as the abomination it is, even during his own lifetime.
