It has everything to do with your main point. You're just not listening.
I'm a gay man. My sister is a trans. People like us rely on visibility (even through marketing budgets) to become assimilated into communities as normal. Without allies, without corporate allies especially, jobs, healthcare (through said jobs), and quality of life are actually difficult to come by.
30-50 years ago, I would never be able to bring my partner to a work function, now its totally encouraged and we can be treated as full members of society together because of acts like this from companies like Nintendo.
Let alone, its not just our acts in bed, there was (and still is) a perception that effeminate men are automatically gay. And 30-50 years ago, when that label was put on you because of your mannerisms, or your lisp, or whatever...you were automatically excommunicated from "polite society." But now we have a culture that is largely more accepting of "traits associated with female" and less abusive towards them.
