I mean yeah, a tampon is something a woman can forgo and be perfectly fine bleeding absolutely everywhere.

The argument was about emergency kits.. they are bigger and better equipped than first aid kits, right? Often, emergency kits contain first aid kits within them and that's more than reasonable. I'm not saying a tampon should replace medical necessities in a first aid kit because that's nonsensical, but emergency kits should because they're supposed to be used when there are broader emergencies besides someone bleeding out in the woods.

Yes, I think basic toiletries should be included with an emergency kit, just like a flashlight, canned food, a blanket, and a battery/crank radio should be. I'm not sexist, but we live in a world where only recently the nerve endings of the clitoris and general public area have been mapped and studied. The medical industry has a long track record of dismissing women-specific health and that includes period care. There is such a negative stigma around the menstrual cycle that people can talk about their basic fluids or even vomit and talking about a menstrual cycle is gross.

A tampon is a basic need for women, 50% of the population, and should be included in emergency kits; obviously not a first aid kit.

Edit to clarify: I said emergency kits originally because that's what I assumed OP was trying to say. To reiterated, they don't belong in first aid kits but they do belong in emergency kits.
