Assuming it ever gets uploaded, I suppose the option of filing a wishlist
bug (or, I suppose, even RC to keep it out of testing at least) is
RC bug would be abuse, I guess. And probably received as rude,
censorship, and thus leading to the opposite reaction.
What about a wishlist for an alternate set of themes/pictures and a
debconf interface for choosing the system default?
On the positive side, a message has been spreaded out in this
thread and I guess that some more people are now aware that hurting
people's feeling is very easy...and that one really never knows where
the line may be drawn.
Have you noticed that the package maintainer indeed did not
take part in the thread, by the way...:-)
