In general, I don't think badger brushes do get that much attention, and even fur coats don't seem to attract the opprobrium they did 30 years ago. The other issues you mention do get a whole lot of coverage, but together they all form part of a large discussion about what is wrong with the world, and that's not really what this little shaving forum is about.
My rather carefully phrased OP raised the question of how we reconcile the ethical treatment of animals with our use of badger brushes, and the fact that most of us are at least giving it some consideration answers that very well.
