Because I cannot seem to leave well enough alone, and because this has been rattling around in my brain for a few days--
Since I've seen it get thrown around a few times in the cultural appropriation debate and the resulting fallout, I'll readily agree that E.M. Forster's quotation is a noble sentiment. It is praiseworthy to want to support and be true to one's friends when they're going through hard tmies.
However, I also feel honor-bound to point out the following:
Disagreeing with one's friends is not betraying them. And telling one's friends that they're being rude and insulting to other people really doesn't count as throwing them under the bus.
(I felt the music was at least slightly appropriate to this entry.)
(Something else I've been ruminating on is whether or not a lot of the fail in the cultural appropriation debate is the Five Geek Social Fallacies at work in a larger cultural setting-- particularly the ones that go "Friendship above all" and "Ostracizers are evil." But I think that's also something that deserves a much, much longer post.)
