Both! And protect profiles who do qualify (see below.)
It's also always good to have a group of folks who are out and LGBTQIA+ to answer questions non-LGBTQIA+ folks may have about features that impact LGBTQIA+ people and profiles, profiles of LGBTQIA+ people, etc.
We are by no means a monolith, and organizing ourselves can help represent that diversity of perspectives. Without at least a little bit of organizing, LGBTQIA+ individuals can often be perceived as an authority on something they don't have lived experience with. A lesbian, for instance, might have a less visceral response to the Find a Grave acronym because lesbians are less likely to be bashed by that word than their male gay counterparts. I was never bashed with that slur; I'm queer enough to be sensitive about writing it out instead of using the acronym, but wasn't sensitive enough to take on the heat of asking others to consider not using the acronym. I've been struggling to write this paragraph for way too long; in summary: there are some conversations that are best served with some intra-community talk before engaging in inter-community talk. Hope that makes sense.
A great example of a profile that I'd love to protect is that of Nancy Brown, an AMAB person who dressed, worked, named herself, and lived as a woman her entire adult life. In 2020, everything about her life suggests a high likelihood that she would have come out as a transgender woman. But we weren't talking pronouns during her time, and the topic of queering history is a complicated one even intra-community! While I chose to use she/her pronouns as a queer person as a way to respect my genderqueer Elders, we don't actually know how Nancy referred to herself. We only have one account of her and that author uses he/him pronouns for Nancy while affirming every other aspect of her gender. A WikiTree marathon related to gender markers caused a marathon participant to misgender her as male a few years back. This resulted in a G2G conversation that did not foster a welcoming environment for transgender people, and I'm grateful to the folks who showed up to try to rectify that.
I hope that helps answer the question of purpose as I'm currently pondering it, but always open to adjustments from other LGBTQIA+ WikiTreers! I guess the tl;dr is twofold: LGBTQIA+ informed WikiTree work as relates to LGBTQIA+ features and profiles, and fostering an LGBTQIA+ community of genealogy nerds for various reasons including but not limited to intra-community discussion and mutual support.
