I did hear we won in fencing .
"We" won one medal, gold, in women's fencing. Did not medal at all in any of the other fencing outfits. Full disclosure, yeah, I used to fence, foil and sabre. And the networks never cover it.
OTOH, the US has never medaled in fencing before, so a gold ain't bad for the young med student from KY.
As for the OP, the media are clearly ignoring the shooting sports wins, counting the medals but uttering not one word about which sport.
As for the naked arc welding, it's likely coming. I was stuck in a restaurant yesterday and they had men's dual war canoe and women's dual kayaking, so I imagine the welding will be in 2024, 2028 latest!
BTW, I call it the war canoe, 2 guys kneeling and paddling for all they're worth. Sure looked like a (very small) war canoe.
