Your whole text reinforces the disdain of Central and Eastern Europeans against selfish Western Europeans.
"For you, "socialist" is a nasty word. For me, here in Europe, we have had a socialist party in our government for the better parts of the latter 20 century, and we have reached a prosperity level that most of the world, and I dare say including the US, envy us for. So someone calling himself "socialist" isn't that big a deal here."
In Central and Eastern European members of the EU the reality is that "Socialist" is being seen as a more tricky version of "Communist" (which in itself is seen as nothing different than "Nazi"). Yes, the Socialists themselves tend to believe being a Socialist is oh-so-different than being a Communist (with a minority being actually hardcore Communists who realize their only way to influence is by using the Socialist umbrella). But since most Socialist parties are in reality former Communist ones (you know, those who enslaved their own nations post WW2), their situation is very similar to those who are sorry for being caught, not sorry for doing something bad. For the majority of the population Socialism has negative connotations (for obvious reasons).
"He would, by the way, be the absolute polar opposite of a "liberal" for the average European."
True. A liberal in Europe still follows the classical liberalism stance of freedom.
"Also due to our political history, where the liberals are usually found at the right edge of the political spectrum."
Not true. And it shows that you're a socialist / social-democrat / leftist yourself (not that there were much remaining doubts by now). European liberals are on the CENTRE-RIGHT of the political spectrum. On the RIGHT-EDGE are, well, right-wing / nationalist / populist movements and parties. But as usual European leftists believe they are the center, so of course a liberal would be so far to the right...
"A "conservative" here is more a centrist than a right wing nutjob."
I fail to see where on this discussion (which is focusing exclusively on either USA or the European Union) conservatives are *EVER* believed to be "right wing nutjobs". The only place would be some Communist propaganda outlets... So now we know even better your position, comrade "Opportunist"!
"If you're looking for poisoned words in the political arena here, I guess you have to reach for "nationalist". That well has been utterly poisoned for good, I think. But I guess that's what starting the bloodiest war in the history of mankind would do."
Funny thing is that WW2 was started by National-SOCIALIST Germany and COMMUNIST Russia attacking and sharing Poland. So let's tone down the obvious lies that the bloodiest war in history was not the direct effect of left wing nutjobs bringing socialist / communist revolution to the unprepared world.
