There has never, in the history of humanity, been a system--religious, social, political, or whatever else--that hasn't (sooner or later) been gamed to the advantage of those who have absolutely no morals, no ethics, and no concern for the well-being and good of anyone but themselves. And that's true even of systems which have checks in place to stop (or, at least, reduce the effectiveness of) that sort of shit.

But when your system is basically nothing more than "I feel like an 'X', therefore I am an 'X', and I should be accorded all of the 'rights' granted to 'X'?" For fuck's sake, it's like throwing a bucket full blood and chunks into the water, and then being shocked when sharks show up! You could not craft a more appealing vehicle for abuse by the malignant parts of the population if you made a deliberate, planned effort.
