As a SW-German, I’d say it is way more a rural vs. urban thing. In the greater Stuttgart area f.i. don’t worry about openly living a gay lifestyle. If you live out in the woods, it might be different, but not necessarily so.
That being said, SW’eners are generally way more conservative towards any kind of “fun” or “flamboyant“ things - legacy of the very pietist history here.
Well, that’s your opinion….
