It's not so much the TV aspect as the cultural differences which are evinced by the things which amuse and annoy us.
For instance, the only transponder I can remember getting upset about the BNP threads on Mudcat was Peace, similarly the unlamented Jade Goody thread aroused a lot of ire in the UK, but none in the US.
Now you have your social misfits and misanthropes in the US, but I can't remember any prurient threads on the lady who had the octuplets for instace. Just general disapproval.
You have the KKK and the John Birch Society, and they seem to be largely ignored by US Mudcatters.
Could it be that the comparative sizes of the two countries is a factor. With we Brits living in each others pockets,figuratively speaking, and while a plane is required to get across the USA, we can drive from one end of the country to the other on less than 24 hours?
It's difficult to quantify what I mean on this one, but basically it's my view that in spite of the number of non US residents posting on Mudcat,it still remains an American website, with the commensurate values attached thereto.
I await the brickbats.
