So it turns out LGBT tartans are a thing and most of the ones I've found look kinda boring but I do like the look of this married couple's personal tartan:
*considers how identity is doomed to eternally fracture itself as worldviews conductive to partial/mixed identity are not politically expedient, and those with complex identity will inevitably be attacked by fallacious No True Scotsman and Yes True Scotsman arguments alike before being splintered off into a new label, dooming themselves to repeat this at a smaller scale*
*reaches an exciting epiphany!*
"Oh dang I hope pride flag tartans are a thing!"
