I think part of the stonewall problem is that they’re not interested in representativeness or participation. They’re really too focused on the exceptional outliers (the most vulnerable, the most marginalised, etc).
It means that all those pretty mainstream and ordinary gay and lesbian people get forgotten. They’re not interesting enough to merit attention. Who cares about the ways in which homophobia continues to create barriers in their lives, especially for lesbians when there’s a more special
group to shout loudly around?
The carnivalesque-as-default presentation of LGB-and-the-list-of-many-letters is not really that helpful to the majority of people the category claims to include. Life is not a pride parade and, frankly, most LGB people are not reasonably represented by sparkly rainbows, fetish gear or whatever - that’s true even if every so often they might dress up and join a pride parade or whatever.
The boring, non-sparkly, issues that affect people’s everyday lives do matter. Pushing those boring, ordinary lesbians aside to focus on drag queens is simply not helpful. Sure, it’s easier from a marketing perspective to show images of trans women in sparkly dresses than to try to present lesbians who often just look pretty much like many straight women (especially given the wide variety of ways in which any group of women might choose to style themselves) doing ordinary things. It’s all more eye catching and distinctive. But it’s not representative.
Stonewall should actually give a shit about representing the significant proportion of the population who just are LGB without needing to be spectacular or exceptional in doing so. Instead they’re off trying to ‘save’ the ‘most vulnerable’, redesigning flags to include ever more colours and just missing the whole point.
