Thank you for your question. I'll try to answer it as clearly as possible. My colleagues will be able to supplement my response.
Intersectionality is a very useful approach to understanding the intersections of gender and sexuality, which can be found in the LGBTQ+ acronym. It's also a useful way to understand that the people in this community aren't only LGBTQ+, but also people of colour, seniors and youth. There are several other socio-demographic factors that come into play, including employment and income level. Obviously, this leads to complexity, and it isn't always easy to make public policies that address complexity.
Nowadays, we have a great deal of research data. Even though the data is insufficient, it enables us to pinpoint where the intersections create specific areas of vulnerability. We could focus on the population group of young, non-white, racialized transgender people. These people are subject to racism and transphobia for a variety of reasons, and they're young and they have fewer resources. I'm also referring here to the complexity in the targets, because we can also assume that older transgender people face specific issues.
Intersectionality is really a reading guide to help us pinpoint the main areas of vulnerability. Of course, this approach isn't a policy per se. However, it can help us guide the allocation of resources and better understand the health needs of specific communities.
