You talk about context, and then come out with that shit?! The context here is that OPs dad misgendered her (OP indicates that this is something that has been going on for a while, to a point where it has caused irreparable damage to their relationship) so by means of retaliation to this particular interaction, but assumingly out of frustration of the constant bullshit he puts her through, she takes a photo of her vagina and sends it to her dad... Both are acting out of malice; ergo, both are cunts.
