Alex: The truth is that cisgender people have not had to consider how their gender, and really most identities are a social construct.

Alex needs to immerse him/herself in some feminist herstory. Trans women routinely call lesbians “Cis women,” as if lesbians and feminists have not been writing about, challenging, and violating gender and gender expression norms for decades prior to the trans movement.

Coincidentally (or not), lesbians and feminists are also the groups that get targeted by trans activists for the most online and in-person abuse.
