If someone wants a world where no one is marked as cis, they must simultaneously fight for a world where no one is marked as trans.

They’re both adjectives, but we have preferences. No, ‘cis’ doesn’t imply that trans people are better. ‘Cis’ implies that trans people are equal. People who object to this equalization are transphobes.

OK, said the pack of hungry tigers. A slogan like ‘Biological first!’ might not work out so well for them. If we’re tied up by hungry cartoon tigers, our best bet is to untie each other.
