Indeed could be the case. What I find is that German is good as an authoritative language. Makes the voice expressions deeper and doesn't include "niceties". This is also a fruit of the culture, Germans very seldom (if ever) apologise. I wasn't taken serious when arguing in German because I would apologise often (Portuguese culture) and often say: "I'm sorry, but you are wrong", just to get a rebuke such as: "So you apologize, you recognise you are the one wrong". Even translating from German to English or other languages you see how direct the language really is. For example, to convince someone to something else we usually start with "If you wouldn't mind, can you please do (...), thanks!", while Germans will often shorten to just "Bitte machen (...)" where the bitte portion is not really heartfelt and doesn't end with a thank you. You'll hear them replying when inquired if this isn't rude behaviour: "It's her job, no need to thank".
