Pretty much tells you completely where this survey is coming from...
Liberals
If only the EU cheerleaders were actually liberal minded (they'd quickly change their state-centric attitudes and get labelled conservatives, despite wanting the status quo to change, lol). I think the US has forgotten that liberal actually means something, and it's got precisely zero in common with the practices of the US Democratic Party.
"Words change their meaning over time"? Yup, and there exists a concept called etymology, whereby words with common root components share similar meanings, which makes any derision of liberal as a political label by those who identify as being labelled a libertarian a little bizarre (because they essentially mean the same thing when you strip the political manipulation away). Labels conferred via political propaganda and philosophies are not the same thing.
