The negativity is not particularly surprising but it is a little immature and has little real substance.
I would suggest that the UK has the most interesting history of any country, and has arguably contributed the most to literature, music, politics, science and sports. Our cultural and political legacy across the globe is simply immense.
Moaning - moaning that the Government isn't spending enough on $current_issue (whether it be education, health, transport etc) whilst simultaneously complaining that taxes are too high.
I would describe the UK as the best country in the world to live. Sure things could be improved but in general we have better standard of living and rights than most countries, (groups like females disabled etc. )
