All of this Olympics gender stuff is reminding me of a moth watching thing I went to. The person showing us the moths explained that the difference between moths and butterflies was distinct, but there's a large overlap. So much so that it's clear the two categories are arbitrary human ideas rather than reality based facts. You have butterflies that go out at night, you have butterflies with those fluffy moth antennae, you have moths that look more like butterflies etc #moths
