Hating to break it to you, but Attributing ANY group as a whole with positive/negative traits is racism. But keep mincing words - probably the only thing you are capable of?
Incorrect. Racism is the prejudice or discrimination of a person or people due to their racial or ethnic group. Not just any group. So no - attributing something to Germans isn’t racist.
No. I just leave this here, from German Wikipedia. Translate it yourself.
„Unabhängig von seiner Herkunft oder Nationalität kann jeder Mensch von Rassismus betroffen sein. Das Internationale Übereinkommen zur Beseitigung jeder Form von Rassendiskriminierung unterscheidet nicht zwischen rassistischer und ethnischer Diskriminierung.“
There is only one human race (Racialization)
Racism is still a problem.
