yes, very good point smilesy - it's so different it's difficult to find comparisons, but we in the UK know it's massively difficult and generally don't try to "fix" it for the US or claim to understand their system through and through.
However, the US posters are very confident (and some EU posters) that they completely understand UK system. So I can't imagine going on to a US board to "sell" our version of politics to them and why ours is better.
For instance, no one can really get our heads around the idea of the "flag" in the US and how proud etc. Understand the initial pride, but flags are now associated with decisions around the world which have not impacted well on local populations so not really for the US to tell us our country or flag is representative of oppressive acts etc.
The language, politics, social history is so different - I find sometimes talking to people from SA that their description of something may "jar"; not as much as back in the 1980s when I'd be open mouthed at some of their assumptions. However, we accept countries have different histories, social history in particular and political systems etc. So we give people the benefit of the doubt.
The US posters currently telling the UK why we're wrong about everything don't seem able to understand the above. That they just might be wrong about what they think the motivations behind a population's reaction to any given situation are.
Common language is becoming an increasing barrier to ease of comprehension now that social media is such an immediate reaction.
We now have US posters saying the use of language here is to be policed according to their social history - is that not just a good old attempt at oppression of old in the end?
Respect different countries are different and that's what makes us interesting. Homogenous offence to everything, something offensive to the UK about how M speaking in SA appears may indeed not appear to be the same reaction in South Africa.
However, as I say I've often found some people's language "jars" from SA on certain issues, so I'm not surprised. However, I'm not saying "they're wrong", it's we react from a UK point of view and it does "jar" for us sometimes in respect of SA.
