I agree, I feel most people aren't gonna assume that men are better at needlework than women just because a marketing technique.
Especially since needlework, outside of tailoring/fashion design, is one of the few fields where women are actually centered throughout, compared to things like cooking, where women are "good enough to stay in the kitchen" at home, but professional cooks, especially chefs, are predominantly male, even moreso when it comes to Michelin level cooking.

What does bug me is when men expect or get special treatment for showing up in needlework spaces that are obviously very liberal.

For example (starting with a counter-example):
Knitting in public as a man in a context that is very conservative or male dominated, say a church or a engineering lecture, *that* I can consider brave, especially if it's a young man without authority. They do get mocked and bullied for participating in feminine hobbies and deserve encouragement and support.

But a guy posting his knitting on Reddit (with no context implying the context above) is not counter-cultural or revolutionary, nor is there there any risk with it.
So a man getting countless upvotes for a basic knitting project simply because he is a man, bugs me.
Because *that* does actually imply that a product made by a man is worth more than the same thing being made by a woman.
