I think part of your problem is that the primary language of many (most) people on this board has, by-and-large, gender-neutral nouns. Now, the board is not demographically typical, and probably has a lot more people with experiences with those languages (including quite a number of native speakers). (I will also note that you make a comment about the German board being mostly male - this board is WAY heavily male; I am not sure what difference that is going to make here, but it's something that's true).
But English is very low on gendered nouns, and even though I've studied languages with them, it's always a bit difficult to wrap my head around. True, though, something like "Baker" is a little different. We have some examples, though, and in general it seems that using the "male" word, at least for us (again, I don't know German), is closer to neutral than using the "female" word, while not really being totally neutral. The examples which spring to mind are "waiter" and "actor". You will get "waiter" used to describe both men and women sometimes, even though "waitress" is also a word. More to the point though, "actor" is often used to describe women who act, or even just one woman who acts, even though "waitress" is also definitely a word that isn't incredibly strange. On the other hand, I've never heard "waitress" refer to a man, or "actress" refer to a man. Again, I don't know how much this is worth, but there you go.
Perhaps the bigger point, though, isn't so much that people disagree with you. Maybe even they agree, it could be done better (though, what specific suggestion do you have?). The thing about "this doesn't matter much to me" comes in though. It doesn't matter that much to most people, in terms of, sure I agree, but what do you want me to do about it? The big point is, we would have to go pretty far out of our way to try to make any kind of change, and the incentive to do that isn't there.
