Die Kirche, die in D evangelisch ist, ist in den USA die lutheran church.
Not true. The "evangelische Kirche" in Germany consists of three different theological groups that have joined together (at least nationally) in the EKD. These three streams are the "reformierte," the "unierte," and the "lutherische," and these three streams are still represented in various "Landeskirchen."
The "reformierte" stream in Germany is represented most commonly in the US by the churches with a Calvinist base, such as the Presbyterian Church in the USA. This stream is the smallest in Germany.
The United Church of Christ is a distant cousin of the "unierte" stream, having been formed some years back by a series of mergers, which, going further back in the merger chain, included the Evangelical Synod of North America. That church body was a direct descendant of the Prussian Union church in Germany, still represented by a fair number of the current "Landeskirchen," such as in Berlin/Brandenburg.
There are a number of "pure" Lutheran "Landeskirchen" in Germany, such as the Bavarian Lutheran Church.
#10 is completely correct. There are other "Lutheran" churches in the USA, including the Lutheran Church-Missouri Synod as the largest. These tend to be very conservative (to put it mildly). For historical and theological reasons, they likely bristle at being lumped together with the other so-called "evangelical" churches in the US (most of whom could be traced to a theology that is either extremely conservative Calvinist or Baptist). But, in practice, they can all be lumped together. Most of these other "Lutheran" churches in the US truly despise and deride the ELCA for being "too liberal" (or even just "liberal"). Heck, the ELCA is even an "open" church that allows for gay and transsexual pastors.
