If you want another example, here is one: do you remember when Amanda Bynes had her breakdown a year or two ago? She posted really vulgar things on twitter and there was a thread about it on GAF. At first, people were laughing; lol she's posting about wanting to have sex with drake, what a weirdo, another Disney breakdown!
But over time, she began lighting things on fire and running through the streets naked, and it became clear that this wasn't just some girl who had grown up and found her sexuality, this was a person suffering from mental illness, and it increasingly became less funny. Again, we could not diagnose her. Most of us aren't doctors, and even if we were, she's not our patient. But it was clear enough that laughing seemed rather mean spirited. It was quite possible that she was suffering from mental illness, and I don't really like pointing and laughing at mentally ill people. Later on, it was confirmed that yes, she was indeed mentally ill.
The woman in the OP is on this spectrum. Am I absolutely confident that she's mentally ill? No, of course not. Again, not a doctor. But it's crazy enough behavior (and not just the behavior itself, but her responses in interviews) that it's something I'd be highly suspicious of.
And again, given that it seems at least quite plausible that she's mentally ill, I'd rather avoid pointing and laughing only to later feel super bad about it if she's diagnosed with bipolar disorder or a disassociative disorder or something.
