I did that myself on HN earlier today, using the fact that a friend of mine had been stalked to argue for why personal location privacy genuinely does matter.
Making up fake family members to take advantage of that human instinct for personal stories is a massive cheat.
If interacting with bogus story telling is a problem, why does nobody care until it’s generated by a machine?
I think it turns out that people don’t care that much that stories are fake because either real or not, it gave them the stimulus to express themselves in response.
It could actually be a moral favor you’re doing people on social media to generate more anchor points for which they can reply to.
It's like the identity actually matters a lot in real world, including lived experience.
In general forums like this we're all just expressing our opinions based on our personal anecdotes, combined with what we read in tertiary (or further) sources. The identity of the arguer is about as meaningful as anything else.
The best I think we can hope for is "thank you for telling me about your experiences and the values that you get from them. Let us compare and see what kind of livable compromise we can find that makes us both as confortable as is feasible." If we go in expecting an argument that can be won, it can only ever end badly because basically none of us have anywhere near enough information.
You're confusing, as many have, the difference between hypothesis and implementation.
The only reason that someone would think identity should matter in arguments, though, is that the identity of someone making an argument can lend credence to it if they hold themselves as an authority on the subject. But that's just literally appealing to authority, which can be fine for many things but if you're convinced by an appeal to authority you're just letting someone else do your thinking for you, not engaging in an argument.
