Not... really? I mean, trans headcanons have different issues where fandom tends to glom onto whatever character least typifies the stereotypical gender norms of whatever they present as and go, yeah. That one's obviously trans. But it's not that common yet, so your reworked "so there!" comment doesn't make sense. And the trans community doesn't decide Kylo Ren is trans because he likes sucking at life and killing people he's related to, so there's another parallel that falls flat.
