What a load of crap. It totally fits in the gender payment gap narrative, but this example just shows the obvious. Women are not fun to watch. I mean lets just for a moment take a step back and remember where modern sport come from - gladiators, and colosseums. Sports are competitive and aggressive in nature, and society doesn't view women that way and it doesn't want to view them, even if they where exactly the same in strength and stamina. But that another thing, men watch sports far more than women and there is a matter of identification. You can always hear fans referring to the victory of there team as if it where there owns (we won!). So pushing bigger payments on women for no apparent reason is sexist. And I totally agree with what you said:

We all have our opinions but ultimately paying someone more for no other reason than for their gender is the same as paying them less for that same reason. It is sexist.
