Apologies if I sounded snippy, or if I demotivated you from commenting. I like your attitudes and topic choices generally; it's just that I'm worried about the effects of creating a precedent for people to be talking about such topics on this particular site. Again, I'm not even confident that the effects are harmful on net, but there seems to have been widespread support of the recommendation to avoid politically charged examples, and it bothered me that people seemed to be letting that slip just because it's what happens by default. In any case, the length of this thread probably suggests I care more about this issue than I actually do, and for now I'll just agree that it would be nice to have clearer rules and bow out.
