Oh yes, it is clear to me that the majority of humanity that we call 'normal' are to some extent mentally ill. Just like how many people can be nudged into ill health just by a cold day due to underlying weaknesses - so too do most of us hold mental/emotional injury/dysfunction that can be felt and noticed in the right conditions.
There are many 'vested interests' that are both sick and also predatorial who will do whatever they can to switch 'respect for life' back through to 'support for death'. The 'positive thinking' approach has allowed this to continue for a long time because many simply refuse to accept that such heartlessness can exist.
