She's the classic upper middle class type of do gooder, with a trendy pinch of soft Labour sneering at this country and the little people in it..
Massive virtue signalling at every opportunity , and I remember her comedy series years ago that seemed to end every sketch with something to affront the middle classes ..epater les bourgoisie ?
I've met many people like her over the years who are loud in their condemnation of 'the deplorables ' while protecting their own privilege and status.
All of this.
Personally, I think that bitching about Britain is biting the hand that feeds, which is rude and disrespectful. No country is perfect but she's had a good life here, including access to healthcare and education and been supported in her career.
Educated at Cambridge, no less, when there are countries where girls can't even access a basic level of education. Not to mention her Damehood. Bad manners to accept an honour then complain about the country that's given it to you. Privileged is the word to describe her, I think.
All of this too. Many people have said exactly what I think/wanted to say on here. I quite like ET as an actress, and I know^ she is not a bad person FGS, but she really fucks me right off (along with other over-privileged slebs!) with her eco warrior bullshit, yet getting planes at the drop of a hat...and living her luxurious lifestyle. WTF are these people trying to prove?! She is an embarrassment! And as for slagging off the UK? What the actual fuck? How DARE she?
If it's that bad, she can sod off and never come back.
And don't even get me started on the 'well the plane was going that way anyway' argument. That is literally laughable! People will do anything to try and win their (lame) argument won't they?
And I agree wholeheartedly with a pp about the young, and how 'right on' they are, and how they blame the over 50s for everything, yet they would never 'make do and mend' or give up their precious £800 iphones, apple watches, expensive tablets, macbooks, brand new flashy cars, and 3 holidays abroad every year.
And no I DON'T have my own car. I can drive, but 90% of the time, I walk or cycle. Also, recycle everything possible, use the same (canvas) bags over and over for shopping, and use as little water as possible. So there! 
I bet the people saying 'bet you all have a car anyway!' have a car themselves PMSL! Eco warriors are usually THAT hypocritical!
