Well said Paul, your response demonstrates to me that when eg the oppressive coloniser to the UK's impact is between white participants the oppressor and repressed it is somehow 'different' than that when its between white and black . Maybe the version of 1066 that is taught should be revisited and not from the victors prospect (Normans) but from the vanquished and the those subdued and oppressed prospective. The fact that England and Ireland became part of the Norman Empire that stretched to the Holy Lands, That the Normans also denied us our culture, our language, our laws. That oppression when put into the context lead to the first form of civil rights and a constitution Magna Carta.
It appears that your education was sadly lacking.
We do all of that. As a Archaeologist first, and Historian second, I'm also rather scathing about the Romans too. Obviously anything pre-Romano Britain is not covered in History as it's not History.
