With all due respect, that is a pretty generalized analysis.  The decision by the IOC and USA Cycling was not made without substantial scientific research, a fact that is lost in basic "I'm not a zebra" conclusions.  I would not be surprised if the policies continue to change as more research is available.

You said earlier that the current social climate is driving this.  Certainly that is true, as social climates are ever-evolving and society is collectively seeking better inclusion for LGBT persons.  There's no reason to believe that old social climates are inherently better.  In fact, history shows that many don't stand the test of time.
