Condition #43 for something being a sport clearly states that it is not a sport if the most severe injury you can get is a blister.
It's unclear to me how the top woman's foil fencer would fair against the 100th best men's foil fencer. Fencing can be pretty random and you can get upset easily by someone much worse than you if you lose concentration. The bouts are pretty short. I suspect they'd do much worse than the best woman golfer than the 100th best men's golfer, though.
I fenced epee in college and women only fenced foil so I can't really judge myself.
