I'm sorry but this timeline and story makes zero sense. For reference, 2014 is about a year before gay marriage was fully legalized in the US and reasonably before the whole trans rights movement started being a lot more public. I went to college in a deep blue state and had practically little to no interaction with any transgender folks, both in my gen eds classes and just overall at that same time period. Someone arriving as a guest speaker and talking in the way you've mentioned would've instantly made headlines in 2014, especially since at least one student would've complained and made it a bigger issue which as far as I can tell it doesn't exist. Nor are there any mentions of said guest speaker, and colleges are generally very public about this sort of thing.
