I don't think Seiler's been diagnosed yet, so calls she be held accountable for perpetrating a hoax are completely appropriate unless overwhelming evidence is presented that she is not of sound mind.
I really don't think most here would ever mock mental illness itself, and it ought not be wielded automatically as exculpation for misdeeds.
I'm withholding judgement because how the hell do I know what's going on? But your bashing is unwarranted, IMO.
When folk automatically mock and scorn and deride the mentally ill, as many have done on this thread, it tends to piss me off. It's heartless, and ignorant.
