It's a direct borrowing from English and is used in the same way as in English, referring to people who identify as LGBTQ+ and sometimes used as a broader term for non-heteronormative identities and experiences.
However, it's important to note that:
* The word "queer" in French isn't as widely used as in English, and may be considered more controversial or less common.
* There are other, more common and preferred terms in French, such as:
* "LGBT" (for lesbian, gay, bisexual, and transgender)
* "LGBTQ+" (for lesbian, gay, bisexual, transgender, queer, and other identities)
* "Personnes LGBTQ+" (LGBTQ+ people)
* "Communauté LGBTQ+" (LGBTQ+ community)
It's always best to use the terminology that the person or community themselves prefer.
