I'm having a go because all you've done is insult the country I live in, Hamm - I didn't know you weren't British, but if you were, you should bugger off as you plan to; if you're not, then don't stay here and bite the hand that feeds you. You'd be the first to disapprove of foreigners in whatever 'your' country is if all they did was put it down. You then went on to say it's no longer a world power, which is total bosh, of course.
I'm having a go at you because you're like so many people who are only too glad to whinge on and on about everything you believe to be wrong with the UK, while continuing to live and work in it, which is two-faced hypocrisy. No-one is forcing you to live outside your country, are they? So, if this is one is so crap, presumably yours is brilliant, so why linger where you hate it and not return to where the sun presumably shines all day, and everyone is blissfully happy? Staying some place you clearly despise is bizarre behaviour, which is one thing - making your usual inaccurate assertions about it is another, and requires correction.
You can say back whatever you want - fortunately, I am living in a democracy where there is relative freedom of expression.
You come up with wildly unsubstantiated critical comments all the time about people, events, and issues - I've argued the point by rebutting your nonsense with facts, by the way - or did you fail to spot that?
