Now, let me be clear, it's far from my intention to say this is specifically about Colonel_Klinck, it is not. I can only have personal conjecture and no certainty as to his origins, as with most on public forums, but in my opinion, some who continually post derogatory comments about the UK must have a marked differentiation between where they are living now and where their heart still lies.
Quite what the UK offers, or their long term goals are, to override their heart and personal values in order to live in this country, is also open to conjecture. Given their hatred of many facets of the UK and her history, there must be a pressing need to be be here, yet be so openly vindictive about their adopted country's history and culture.
