Hey, it's only a matter of time before they try to put trannies into Olympics. Or have to tell trannies no, which is going to be spectacular in its own right.
At present, I think trannies can participate in the male competitions (like gays, bisex, etc.,) although maybe some hormones are banned by the Olympic drug control committee. Imagine the butthurt for the tranny that want to participate to the Olympics and has to be identified as a male.
In the future obviously there will be specific categories for trannies, and all the other sexual categories/orientations that will be created in the meantime.
In the future they will create also specific competitions for specific religions: so you will have olympics 100m for christian/trannies as a different discipline than olympics 100m for islamic/ females. Atheists will be banned altogether obviously, because their mere existence is offensive for all the other religions.
