Best greetings and saludo.
How nice
And a Spaniard too. This is called today "multi-culti" and was called in former times "normal". And I don't understand why you are interested in world war 2 in this context.
No. I don´t have Spanish nationality, only German. The WWII context: You claimed people try to become German by wearing a brown shirt.
Who cares about nationality, except idiots?
First of all is "German" not a national identity. My national identity is (1) Bavarian (2) European (3) German ... For me is for example the mentality in Switzerland much more important than every nonsense the Prussians ever made. And I understand the mentality of Friesians much more easy than the Hessians in Bankfurt.
At least the Prussians offered freedom.
What a nonsense. The Prussians were an army which owned a state. They had conquered one by next German country and made them to their colonies. They excluded Austria from Germany. They forced even our beloved Bavarian king to betray Bavaria and "to agree" with them. In the end they tried to make out of everyone in Germany a "Hanswurst" (=Clown), who fullfilled orders, independent how stupid this orders were - and the Prussians prepared in this way the way for the worst clown the world ever had seen: Adolf Hitler.
Nobody told you what to think, what to believe, ect.
"Fake News" from the time after the holy empire had died. The Prussians made for example a culture fight against Catholics - not very tolerant, isn't it? And it It was by the way the Prussian Catholic Joachim Fest who was the first man, who was able to paint a realistic historical picture of the person Adolf Hitler. His father said about Hitler during the time of Hitler:
"Hitler is such a damned good liar, so that even the opposite of his lies are lies again."
My identity remains German.

I did not see this identity. Now I see a poor guy, who has big problems with his identity.
The real, my, German identity includes the German nations as a unity.
Unity?
When you argue like you do, all nations would fall apart.
So what?
Second: A German is a Catholic - like your father - or a Protestant - like your mother. (By the way: The Spaniards did forbid in Wuppertal from 1625-1627 a protestant church service. Funny, isn't it?) And Germans today are also sometimes Orthodox, what I love very much. So if a German is a Christian then he is a Catholic, Protestant or Orthodox. And a German of this confessions is in the German language a "deutscher Christ" (a Christian from Germany) but never a "Deutscher Christ" (a German Christian). The German Christians were a Nazi-organisation, which tried to overtake the Protestants in Germany. They tried to eliminate the Old Testament and all Jews in the New Testament. And out of one of the minor characters of the New Testament - the Jew Jesus the Christ - they tried to make a son of a German soldier, who fought with a sword in the hands against his own people. Dietrich Bonhoefer and other Protestants founded as a reaction to this organized Nazi-movement the "Bekennende Kirche" - the "Confessing Church" - and excluded all "German Christians" ("Deutsche Christen" not "deutsche Christen"!) from the Christian Community. So to say "I am a German Christian" means to say "I am an enemy of all Christians in the world, independent from any confession of this Christians".
You cannot claim to know the religion of my parents. Not even I know it.
Ask them.
I came to a foster family at the age of 8 months.
Good grief. So why do you think your biological parents were important for you? You are a child of god as everyone is a child of god. And your social parents overtook the responsiblity in the eyes of god to educate you. Did you love your social parents? Did they teach you well?
Germans can be baptists too, by the way.
Baptists are Protestanst are the same in our view of the world after world war 2. The way how Hitler tried to overtake the Protestants - what has still today negative effects for the Protestants and all Christians in the whole world - was a warning for all Christians in Germany not to let reduce the christian religion to powder.
But we didn´t go to church but to a private Free Church.
I guess now I understand why you are so crazy. "Private free chuch" - and you are an atheist, isn't it?
When I say I was raised German-Christian, it means German and Christian.
You have the ability not to hear what others - in this case I - say to you. This is typical for the Anglo-American world. So let me tell you: I love it to be a Catholic. In my eyes the Christian religion is the best of all possible religions - but I am also used to think in alternatives. The alternative for the catholic church (and the orthodox church, what are the same for me) I see in Buddhism.
In Germany existed a Nazi-government: Fascism and Nazism are not the same. Hitler used fascistic ideas - but the fascism in Italy or Spain was for example not antisemitic and the Spanish or Italian fascists made not death camps in industrial dimensions as the Nazis did - nor did this people continue a war for years while they knew they were wrong and lost.
It doesn´t change what I mean. If you are interested how the political mood in the Wehrmacht was in general, I can recommend you this excellent read:
Die unsichtbare Flagge – Wikipedia
A doctor in world war 2? No. I don't read it. The last time when I read what an army surgeon wrote about war - it was 1618-1648 AD in the 30 years war - I wasted to much time to feed the sharks afterwards.
