The zeroeth rule of Gender Club is 'you do talk about gender club'
The first rule of Gender Club is 'you decide your own gender, and whether you disclose your gender to other'
The second rule of Gender Club is 'you may not assume, assign or allocate gender to another individual'
ONLY posters (or individuals not posting) who have declared themselves as cis-gendered may be referred to as cis gender. Otherwise you're misgendering, which is definitely against the rules of Gender Club (see above).
And yet we see individuals assigning cis gender willy nilly all over these boards, and cocking it right up. It's complete bollocks, it's not even hard. If you assume, assign or allocate cis gender, you're a dick, you're ballsing it up, you probably deserve the sack.
I trust I've made myself scrotally clear.
