Move to Japan, your sympathy really becomes tested when you see how people behave here.....

Yes, when I spent a year there, I became aware of this. The enlightened and refined elements of Japanese social etiquette run broad and deep, and
present a rich body of knowledge and know-how.
I remember thinking that if the entire concept, detailed and explained, of Japanese 'savoir-vivre' were taught and learned in Vancouver and elsewhere, it could a catalyst for social change.
For anybody studying any form of architecture, engineering, but primarily city planning, and even social work, making the study of this a core part of any first-year curriculum might sound radical, but would surely guarantee a solid handle on Japanese social engineering and methodoly easily transferred into the Canadian context.
It seems to me that the homeless who are sleeping in the tent cities in Vancouver are a mix of
*those who are mentally incapable of taking care of themselves and need to be hospitalized and cared for,
* and for them we
need to take better care,

Agreed, and/but would this not necessitate a larger sector of the economy dedicated to such? And if yes, and if all good, how will the working public react to the inevitable tax increases?
and those who are simply just losers......
Criminal junkie assholes who live on the streets because they don’t want to even abide by the simplest rules of social housing or other shelter facilities.

... to finish your sentence, how should they be dealt with? Specifically
'Part 3'
What we need to do is find a racist, sexist or homophobic comment that each one of those in the parks have said in their lives, such as refusing to list their pronouns, publish them and then hopefully they lose their support from the far woke left.
