We, in Ireland , suffered as much as anybody from British colonial expansion but I think that we need to accept what happened in the past, learn from it hopefully, and move forwards.Look, at the very least he was up to his elbows in blood by encouraging the continuance of Brazil's slave trade. At the least. He also looks on the hook for being a slave owner too if his contemporaries words are anything to go by.
Bottom line: I dont know what his standing was amongst people during the times he lived in, but in today's society he has to be seen as a thoroughly reprehensible character who profitted from human trafficking.
Judging this any other way is to excuse slavery.
I am much more concerned about the inequalities in the world today in terms of racism than what happened more than one hundred years ago.
If we put as much energy into rectifying what is wrong now rather than what was wrong more than a century ago it would be much more productive.
Slavery hasn't gone away, it still exists today... why not talk about that ?
