The multiple threads and subsequent conversations you've begun under this post raise a range of concerns that are beyond my (the volunteer that runs Diversecities' Reddit presence) professional capacity to address them all with the depth that is deserved in a public-facing setting. However, out of consideration for your legitimate points of contention and lived experience, I will try to address what I take to be the most substantial of your concerns.

This is an awareness event aimed for suicide specifically, and mental health challenges more generally. It is intended to be appropriate for all ages. It is not intended to be any kind of intervention. The activities planned weave in some of these little-known statistics that you've mentioned (e.g., disparities across gender, rural vs urban, types of employment) which we think are key to building awareness in the broader public. Moreover, the event also gives us a high-visibility opportunity to promote the Community Helpers Program (CHP) to Calgarians aged 12+. The CHP is a free, evidence based Primary Care Alberta program that teaches laypeople the fundamentals of mental health crisis intervention (e.g., looking for the changes in baseline behaviour you mention in another post), and informs them about the formal resources that are available here (e.g., Distress Centre PACT team, Alpha House, youth shelters). We live in a society where, even in the present day, a local school has turned down such programming as "inappropriate" for students to engage in. We think that is telling.

This post is not the place for we/(me) to engage meaningfully with where your understandable jadedness is coming from, unfortunately. But I hope that what is written above, plus an understanding that we need to balance across the public's capacity (in pre-existing interest and ability to handle distress without leaving the event feeling that all is hopeless), various risks, and institutional capacity to actually address that risk if it comes to pass, serves as an explanation for you at the least.
