If I was going to make assumptions about British People based on threads that appear here you all:
Need to LTB
Fret when someone knocks on your door so you don't answer
Your neighbours are either busybodies or make a noise and are therefore anti social. Diagram obligatory.
Very Eurocentric "I wouldn't want to live away from Europe" I couldn't bear to live somewhere that didn't have history or culture" etc. News flash! all countries whether they are old or new have a history. Just because it's not your Eurocentric one doesn't make them any less valid.
The racism threads. "Is Britain racist"? Usually followed by posters saying oh no there's no racism here even despite being told by many non white posters about the racism they've experienced in Britain.
Brexit. Need I say more?
Meghan Markle threads see above.
Your media is appalling I. E the hounding of Princess Diana, Meghan Markle, etc. Granted, Oz media isn't the greatest either but the UK is home of The Daily Mail and The Sun and we all know what they're like.
OP what exactly do you want to get out of this thread? Do you want to feel smug and satisfied that where your friend is moving to isn't perfect? (nowhere is).
Once your smugness and satisfaction has abated then what? Your friend will still be going and you will still be where you are. Instead of asking people to find reasons for why my country and my people are so awful spend time with your friend and create lasting memories that you'll always remember.
You won't know when you might see her again and wouldn't you want her to have a happy send off? She's taking a big leap into the unknown and her gushing is probably a sign of nervous excitement.
I can assure you we're a friendly bunch over here and are very welcoming of everyone (except if you behave like a dickhead) yes there is racism (no where is immune from it even the UK) but we are a lot more accepting than some are claiming.
I wish your friend the best of luck on her new adventure and hopefully you can visit one day so you can see for yourself how nice and welcoming we can be.
