Of course you will, and such is your choice, but you should at the very least accept that the way you consider it is far from "the bottom line". If you had done more open and extensive reading into the subject you would have understood that, at least.
As to your question of transgender women competing in sport, it's clearly a separate issue from transgender women in society in general. The way in which this person was treated ought to be seen as shameful whether or not you think that transwomen should be able to compete in sports.
But after having dodged the question for a paragraph... I am undecided on that. It should be down to the entrants concerned and the referees. As long as the choice of living as a woman extends beyond sports, though, it becomes pretty pathetic to assume that it was purely a cynical exercise designed to allow the individual to win competitions. If someone "became" a woman for a few months, or whatever, won some sporting events, then "reverted" to a man soon after then they should be banned from the sport and any medals revoked, ie treated same as drugs cheats.
