Its weird how you guys are so down to make jokes, you'd think we'd be able to joke with you about things as well without receiving death threats or being told to not play the victim (I am in no way a victim as my brain works and I can think independently outside of the country I was born in).
I think UK's education is pretty bad, I agree with you even if you are joking. As I am a functioning member of society and I don't gain any value from fighting for my country in online forums I take no offence in you stating if my countries education is good or bad, even as a joke.
"Us" talking about wealth inequality in your perfect country (I have never done this personally as once again, I gain nothing for fighting people about their nationality) shouldn't offend you, if its true, then its true and hiding from it and being proud of your country regardless makes you the problem, if it's false then once again it shouldn't offend you as it isn't real.
