And this reaction of yours is a prime example of jumping to conclusions based on political views.
You can argue, that this bone was used for 400 different things. Without context, arguing that it’s definitely something about menstruation is just pseudo-feminist circle jerking. They just choose this interpretation because it fits their views and goals. That’s unscientific.
What you’re doing here is also not much better. Instead of actually engaging with the argument I brought, you just assume, that everyone who disagrees with a pseudo-feminist interpretation of a bone, must be the enemy. That is not exactly scientific.
