Well, I have historically started quite a lot of BS threads criticising UK politics. Olly I think is from the Republic of Ireland.

Now, as to gobal warming, Ireland would largely disappear before the USA other than outlying regions got more than a bit damp. Quite a lot of the UK would too (including my house, on the 5 metre line) so we get a bit vexed about the fact that the vast preponderance of climate change denial comes from and is funded by the US - and that the connection with big money suggests that such denial is for self-serving reasons.

Add to that that by the standards of most of the rest of the world, what the US calls far-left is pretty much far right. And that US money tries very hard to export those standards to other countries (for example the union-busting law-firms in the UK largely came from or were funded by the USA - consider Grunwick).

Finally for this set of examples while there is much wrong with UK politics, we don't have anything like the expenditure on propaganda here that the US does, and our lobbying system is nothing like as bent as the US (although still far too bent) and although the corrupt influence of Murdoch here is toxic it probably cannot compare to the effect of Faux news in the USA.

Sorry. US politics needs more cleaning up than most other places (with the possible exceptions of Italy and Afghanistan and Pakistan).
