Because cows are better! (joking) In thinking about it, I suspect it is because cow cheeses can be very different from one another from the start, whereas the basic structure of goat cheese does not change. It can be fresh, aged, have additions on the outside, or added in, but it is basically the same phyical cheese to begin with.
Feel free to start a discussion about non-Euro cheeses if you're inclined. The forums are not super healthy right now so some discussions about that could liven the place up.Also I feel like the discussion about cheese is so eurocentric sometimes, it's tiring.
