Lots of complaining that too many of the Winter Olympic sports aren't real sports. That curling has a competitor who is pregnant seems to torque people off. Of course, curling in general seems to bother them. They have a point. My ultra-athletic younger brother, All-American in lacrosse, picked up curling for one season and went to the HS North American championship as an alternate.
It's a skill sport, and the Winter Games are top-heavy with skill and technique sports: figure skating, ski-jumping.
But so are the Summer Games. Fencing, archery, synchronised swimming. These take athletic ability, especially at top levels, but they epitomise skill sports.
The winter games don't have people banging into each other, for one, except for hockey. No boxing, no Greco-Roman wrestling. Judo. Field hockey. OTOH, the Summer Olympics has stuff with horses. Dressage. That has to count against them. And rhythmic gymnastics. Diving, freestyle skiing, gymnastics - pretty similar. Distance running, distance swimming, cross-country - about even up. And the Winter Olympics has got a big advantage in fear sports: Downhill, luge, ski jumping. And biathlon, a really insane combined sport, where you have to hold your hands still and shoot things while you're shaky tired from cross-country skiing.
I call it a wash. Except for ice dancing.
