Britain did run riot and impose it's laws and cultures on many countries creating the empire, why?, because we were more switched on and educated than the countries we ruled..
If those countries had been able to they would have shafted us, it's that simple.
Life was simple, you were stronger, cleverer, you exploited the fact.
To equate what went on hundreds of years ago to what is happening now doesn't balance.
I'm fed up hearing self righteous left wing pricks apologising for what Britain did to the world.
The British people were better educated two hundred years ago than very many shit
