I think anyone bashing a country but still goes there is some kind of moron.
Unless it's a blatantly lying, double-standard hypocritic politician.
At least I won't ever go to any of the countries I hate.

I was born in England and I've lived my whole life here. I don't plan
on leaving, but I still think England sucks.

But maybe Finland sucks more? Even if it does, won't stop me bitching
about something in Blighty (traffic, drivers, nhs, education, tv, sport
weather, jobs, the economy, tax, crime, etc etc etc).

How do you know you hate a country without going there? Catch 22 eh..

Some people just do.
Though it's a mystery to me why the hell they go there anyway.
