This could just have to do with me and the people I know (I know that I shouldn't generalise) but I wonder if anyone has noticed anything similar.
I have Facebook friends in America and Facebook friends in the UK. My American Facebook friends are always talking about politics. (Sometimes I agree with them; sometimes I don't.) They have long discussions/debates about various, specific political issues - gay marriage, healthcare, the economy, etc. They are constantly linking to news articles and web pages, including Youtube videos, that have a political message. When I lived in the US, I took part in long political discussions with people face to face.
Here in the UK, the only time I have ever heard anyone I know discuss politics, either on Facebook or in person, was before the general election, and not much more was said than, "I hate the Tories. I hope they lose."
Is it just these people, or has anyone else noticed that Americans seem to discuss politics more openly, and in more detail, than Brits?
