Did you forget what you said before? It was, "If someone was REALLY suffering from [gender dysphoria], they would not give a toss about using it to ‘manipulate’ someone"
Your "direct" question is completely unrelated. Why are you even asking?
You claimed that people with gender dysphoria basically can't be* manipulative. I'd assumed, and replied accordingly, that you meant "because they have their own issues to worry about". But that relies on a false premise, which is what I pointed out.
It's not the only possibility for what you meant, admittedly.
Perhaps instead you mean that the nature of gender dysphoria makes so that people can't be manipulative. But to establish that you'd need either direct evidence (e.g. studies) or at least some reason to believe that gender dysphoria and manipulation-prone personality traits like narcissism and sociopathy are strongly inversely correlated. Otherwise, why would one expect that the gender dysphoric don't express the full range of human variability in other aspects of their being?
* If your claim was weaker than "basically can't be", then Phoebe's original point which is that one needs to be aware that people with suicidal ideation (and may need help) might also use that manipulatively (and one shouldn't allow oneself to be abused) wouldn't be countered by what you said.
