Possibly. It's not uncommon for folks to use gay to mean queer/LGBTQ and unintentionally exclude folks. It's a holdover from earlier gay rights and gay liberation movements. The history there is complicated.

You also see folks specifically omit the T these days (LBG) to specifically include trans folks.

To be clear, the OP sounds like they are a good person and I'm not accusing them of anything negative! Just noting that some folks might interpret the URL differently than intended.
