Britain wasn't the only, empire though, It's just the one we, here in the UK, hear about.
We also hear about the ramifications of other empires and have the ills of those impuned upon us.
Most countries (yes, even you Ireland) have colonised others at some points in their history, almost always dismantling at least part of the existing culture. The British Empire wasn't as a bad as that of some of our close European neighbours... but I never get a proper response to anything said about that!
If someone could write down what it is that is required of any colonising country to 'make good' show adequate contrition etc. Frankly, whilst I can see the effects and understand how horrible some of them are, I can't see what is supposed to be done about it.
Offers of help, financial and otherwise are often said to be patronising, or an attempt to 'get back in'. So what, what is to be done?
