Why single out one counry? Because that country was singled out by itself - the anniversary involved is the date at which a British Government outlawed the slave trade.

That anniversary is indeed something to be proud of - but it only happened because it was recognised that the slave trade was something to be ashamed of, and that Britain had up to that tiem palyed a major role in it.

Insofar as it is possible for people to be proud of Britain for its role in the abolition of the slave trade and the fight against slavery, it is right for them to be ashamed of what Britain did in developing and carrying out the Atlantic Slave Trade.

I do not think that the people who fought to end the slave trade would disagree with that.
