I know we've addressed your concerns before, but I'll kind of reiterate it.
I moved to the UK to experience life outside of the US. I busted my tail getting a degree that would set me up to live outside the US and experience other cultures and countries.
One of my favourite things about living in the UK is not being bombarded by US politics anymore. Last year's presidential election was AMAZING as I didn't have to watch all of those horrible ad campaign commercials during my favourite programs.
Most of us use this website as a way of learning from other Americans how to go about living in the UK, whether its visa status, naturalization, what shops are carrying American foods at the moment, a bargain airfare to the US for the holidays, the difference in medical care, etc.
You will find that our news section is mostly stuff that affects those of us who don't live in the US anymore (how parliament is proposing making immigrants pay for NHS, changes to the financial requirements for visa sponsorships, etc.).
Of course you are welcome to post anything you like about stories that are interesting you and some people will share in the enjoyment of the banter. I just think the majority of us are very happy to have emigrated away from the US media.
