I really wish there was an alternative for complaining/publicizing stupid shit that businesses do. Last year I had friends working at a Target when that bomb threat bullshit over Pride merch happened - their store refused to let the employees EVACUATE after a threat was called in. Twitter would have been the place to shame that.
In context, no one is harassed/discriminated against/barred from housing/barred from employment/barred from accessing medical care because they are cis. There is no world in which a cis person is walking down the street, hears “hey cisgender!” and gets the shit beaten out of them.
