Enter German and Gendering: You can not say Programmer to address all Programmers in the room. You have to call them Programmerin und Programmer or Programmer:in or Programmende. And yes, most of these words aren’t even German but if you don’t use them you are a Grammar Nazi.
And btw, the fact that we address females with “die” does not mean we want them dead, thank you and have a good day.
