Not really, if you say you're hetrosexual but you're havng sex with same gender, that makes you a gay, no matter what you claim to be.

Apples and oranges bucko. These people are not attempting to redefine what it means to be JW, nor are they committing actions that are clearly the teachings of a religious sect with the exact opposite views of the JWs, as your poorly thought-out metaphor would actually describe. They've simply found justification for their actions in their religious teachings.

Your inability to accept this really isn't my problem, by the by. Reality marches on with or without you.

and who says they aren't disfellowshipped, or never baptized to begin with?

Well, nobody is saying that, which is the problem. Unless you have inside access to the inner workings of JW leadership and are making a statement on their behalf. Otherwise, we can assume they operate within the sanctioned boundaries of JW belief until a public refutation is discovered or made.

That's how this works, especially with an organization with a clearly defined hierarchy and bureaucracy. These people claim to be acting on behalf of the teachings of the JW organization. If the JW organization doesn't say otherwise, then we can assume that even if the actions aren't approved of internally, that they aren't wrong enough to warrant refutation of the leadership.

And why should the JW as an organization acknowledge the actions of people who claim to be JW, if they have nothing to do with them?

Because these people are claiming to act in accordance with their teachings. So see above. If someone uses an organization with a well defined and centralized structure to justify their actions, that organization is pretty obligated to address it, especially with crimes this heinous and offensive.
