> Relaxing neck is... checks notes gendered somehow?

Yup, lots of things are gendered. I know it's a bummer, but here we are.

This, for example, would not be considered a traditionally masculine pose, despite the facial hair:

I wouldn't call it masculine or feminine. I would call it a bit shy and a touch inviting.

I understand people 'think' a certain way... but there's also objective reality - where the source of 'masculine' and 'feminine' are attributes or properties of the subject or object in question - is not the subject or object themselves, but in the perception of them (by themselves in the case of living subjects; or by other's in the other cases).

I Understand your point - I disagree with respecting people's opinions of such archaic mentalities (as old dinosaurs should get with the times or go extinct), I just don't support machismo/sexism - and this seems like such a clear example of this - judging a pose in a gendered way (and implicitly saying there is a superior option to choose (masculine) - that's the quite part) renders (to me) that person's opinion on other subjects suspect: due to the fact I can no longer trust their opinions aren't routed in sexism.
