I’m not going to disagree with your basic idea about non-binary gender or gender fluidity. We do need need to change our collective thinking and for that to happen, we do need people to force that change.
I just can’t agree it’s a crock of shit. I feel like people simply slapped a new label on an old thing and turned it into a “modern issue”. My childhood celebrity crush was David Bowie, you can’t convince me gender fluid is new. Does anyone watching his performance with Annie Lennox really care which one of them has what plumbing? For both these performers being themselves meant expressing any and all genders at the same time, there just was no label attached to it yet.
That label is both a problem and a solution. On one hand, we need the language to talk about the thing, to reach an understanding, which enables the change we need. Frankly “the people who deliberately refuse or naturally fail to adhere to assigned gender roles in society” is a bit of a mouth full.
On the other hand you have the people who try to hide behind the label fearful of the change that could be brought about, or those who would bully others into the motions of change and don’t care about actual change in thinking. (to be fair, they might also believe fake it till you make it works somehow)
What I think we need, is more things like male models advertising push-up bras.
