Grappler - reading the article, it's a joke that any of them are being considered for the olympics. And also a joke that some "sports" are still in the olympics, especially if it's based on, for instance, antidoping protocol, when athletics has had nothing but a string of problems with doping problems at elite player level.
It is a bit rich that the article says that Taekwondo has been beset with controversies since it has been in the olympics. No more so than many other sports I would argue. Outside of the olympics boxing has no end of controversies as a result of the professional bodies inconsistencies yet as a sport it is still not questioned for inclusion ....... it's taken for granted. Should there be a more open and transparent process whereby all the sports are up review.
The reality is that the long-standing sports are quite heavily funded through their national governing bodies, which probably gives them a lot of lobbying power.
