I saw it coming.
This is why the mental illness thread shouldn't have got so much hostile treatment from you people. Perhaps the OP in that thread was off in some places but he was right in that you bet your ass the government would love to declare each of us mentally incompetent and our opinions evidence of insanity, then take away our votes.
No one in that thread to my knowledge ever downplayed the threat of government involvement in mental health.
However, thats a different story from lspooner trying to quantify all mental illnesses as either attention seeking or brain parasites, simply because the existence of the concept of mental illness is troublesome from a liberty perspective.
Governments will use any excuse to gain more power, gun crime, drug use, prostitution, mental illness, health and safety, how you raise your kids, you name it, this however does not automatically make it invalid to talk about these concepts in separation from the intentions government may have for them.
Just as its not necessary to deny the existence of drug harm, or perils of work hazards to be against government involvement in those areas, the same goes for mental illness, and lpsooner completely flies off the handle when it comes to mental illness, going so far as to claim anyone who has hallucinations is either making it up, or just indulging themselves, and that it isn't possible to have negative thought processes or sensory disorders that are out of your control, or if there is, its just a disease, it cannot be a malfunction of the brain itself.
Its an LOA style borderline lack of grasp on reality out a sincere willingness to believe something isn't so with no regard for whether or not it actually is or not.
In short, yes denying reality and making outlandish claims you can't back up completely destroys your credibility and damages the rest of the otherwise good message that government shouldn't be involved in mental health.
If he wanted to start a thread about the dangers of government involvement in mental health, i'd be happy to agree with him, but he didn't, he started some batshit insane thread trying to deny the existence of quite easily provable mental illnesses because they cause problems for his philosophy, and he'd rather just pretend non of it exists.
