I think everyone is reading this as NPS not allowing Jane Employee to show up in uniform at Pride and hang out. Maybe they’d frown on that. But what appears to be happening is that employees are petitioning to march in Pride parades, or otherwise somehow participate, as they have in years past, and which supports the LGBTQ+ Special Emphasis Program of federal agencies, and NPS is letting those requests sit.
Couldn’t you submit your own attempts (or a commission) to GitHub, or directly to @aeharding@vger.social to consider for inclusion? I’d personally prefer for the primary developer to focus efforts on continuing to make app functionality awesome.
