So if you discovered your brother in law cheating on your own sister, you wouldn't tell your sister because it's "none of her business"?
Also the leak of information will not "destroy lives and families"; the acts that may do this are already done. Don't kill the messenger they say.
Did you even read what you were responding to?
The acts are done in secret. The reasons for the act itself may not be as clear cut as you'd like to believe but you'd have no reason to tell someone that news beyond scratching your own moral itch. Giving someone that news may
devastate them and it might not be your place to do so.
Also- if I had a sister and I found out that she was being cheated on, I'd certainly have a word with her husband. But even then, I'd tread lightly. There's no blanket approach to what is potentially an extremely complex emotional situation
that I'm not even a part of. And I certainly wouldn't want her to find out from a bloody website.
To a lot of people, cheating is an asshole's choice.
You tried to fluff it up and sugarcoat it with vagueness and no examples of why it may not be a horrible thing.
I'm not fluffing anything up. I had a relative that cheated during her marriage because her husband was emotionally (later physically) abusive. She confided in somebody else that she had started sleeping with, because that person provided her with intimacy that her husband no longer did. He didn't know but it ended up demonstrating to her that her relationship wasn't normal and she was able to end it after the affair. If she'd been outed on a website I think that the marriage would've ended a lot worse than it did. I've seen (exposure of) cheating tear apart sections of my family but I've also seen it help some of them to fully grasp the difficult situations that they found themselves in and to act accordingly.
not surprised GAF has a cheater defense force
I'm not surprised that GAF has a group of people that feel morally superior to some people whose situations they mightn't fully understand. But here we are. People are quick to condemn the act, without questioning why it even took place. Sometimes it's the symptom of a wider problem in a relationship, as opposed to being the problem itself. If my wife cheated on me, my first question would be "why did you?", not "how could you?" And if she felt that she needed to go that far, I suspect that I'd already know the answer to that question.
I don't think that cheating is the best course of action to tackle the problems that someone might encounter in a relationship but I'm also not going to sit in judgement of someone else's decision to do so, nor will I applaud it being dragged into the public domain for all to see.
