mental illness comes in many forms. People do not all need to be 'kept' (spunds like inprisoning to me) securely woth carers at all times, for the most part. You will know many people affevted by mental ill-health, but if they know this is yoir view, you're not a safe person to tell.
Institutionalising everyone with mental illness is barbaric. Most people can live their life with aome support, whether that's drugs, counselling, carer assistance or a combination.
Some mental illness is transient
Some is life-long
Some is environmentally-caused (through being assualted or sent to war, for example).
Most people aren't a danger to others, others are a danger to them, in part because of ignorance similar to this. I'd encourage rethinking your position and gaining education on the subject.
