If we do manage to escape the heteronormative crab bucket, we're in a precarious place — scuttling around on the beach on our own — so it's highly tempting to join another crab bucket, with its own sets of rules and ideologies. Hence homonormativity, and, indeed,binormativity, polynormavity, kinknormativity ... There's a certain irony in people looking over at the mainstream bucket, laughing at the crabs being pulled back in, not realizing that they're doing exactly the same thing.
