I really enjoyed Ide Cyan's "Timeless" on the Feminist SF blog; it's a polemic on Time and social change, and was sparked by Ide's notice of the ubiquity of the defense that a sexist or racist or otherwise annoyingly biased person was a product of their time. This sets up a framework in which "now" is seen as a product of progressive linear evolution with Now and Us ethically on top. I agree with Ide Cyan that this is a false construction, a construction in which Time stands in by a trick of rhetoric for individual responsibility and agency; a construction that is deeply harmful.
The part has become the whole.
It’s very, very convenient. It’s very, very easy. And it means the oppressed vanish in a puff of rhetoric.
Her concluding paragraphs using synechdoche and the body (namely, assholes) was hard-hitting, outrageous, and deeply funny!
