In general, all Americans I met in person so far have been quite likeable.
Apart from the Military police of course, but I have yet to meet a likeable German military police member either.
The republican party is an interesting thing, from my eyes seems to be composed of fiscal-discipline-state-rights (is the term right? I mean people who see the USA as a coalition of individual states)-people. They seem to be kinda equivalent to the German CDU/CSU. With them I tend to happily disagree while completely respecting them on a intellectual level.
Another part is composed of highly independent minded anti gouverment persons, with whom I, as someone who has actually experienced a (fairly) totalitarian system, agree quite a lot in principle. I just dont agree on specifics concerning gun control etc. .
The group that I fail to understand is the religious right.
While I do see them as much more egalitarian and democratic than the Catholic church, (afaik: Evangelicalists say: "Everyone can read the bible for himself and use common sense for the rest", Catholics say "The Pope knows best") I simply do not think that matters of belief have a place in politics.
I think that, concerning beliefs, religions and ideologies, a state should insure that all beliefs respect the law and that all beliefs have equivalent rights.
It should in my opinion, not endorse one over the other.
Establishing an amount of tolerance in, especially Germany, was a huge leap ahead historically, which is why I (and every German I know) are particularly opposed to people claiming to fulfill gods will against the "unbelievers".
What actually scares me are the neocons, their newspeak simply brings up to many bad memories, like a certain "anti-fascist-protective-wall".
"Homeland security" translates into "Heimatschutz" in german, which is a term with a strong NS-association. I also do not get why the Reps, who have created this huge ministery, are still supposed to be the party of small gouverment.
Bottom line: From my understanding of republican policies, this means, small gouverment, individual rights and fiscal discipline, I have problems to see how Bush and Cheney were/are republican.
P.S. It appears that John McCain represented this original republican party in the 2000 election, I am unsure that he represents it now.
P.P.S. What most Europeans do not know is that, over the entire history of the US, democratic presidents were significantly more likely to engage in foreign conflicts than republican ones. Once again, something that no longer holds true with the current "republican" adminstration.
