Indeed. Any language is going to sound angry if shouted. Really, if anything, I might be inclined to say that English sounds rather more forceful than German in most circumstances, largely on account of all of the hard T, K and P sounds, which have softened to ts/s, ch, and pf/f in German in most of their shared non-loanwords. Not that forcefulness is necessarily a bad thing; it also means that theres a much broader assortment of “energetic” words in English than one might be available in German. “Stechen”, for example, somewhat lacks the emotive power of “stab” (at least in their unmodified forms). But every language excels in different circumstances.
