I Think people are being deliberately obtuse here about your DD being LGBTQIA. It's used everywhere as a coverall for being anywhere in the LGBTQIA spectrum but some posters just want to play silly buggers for some stupid reason.
Yes, it’s used as a catch-all term for a large and disparate group of people, which is problematic in itself as other posters have outlined. To describe an individual as LGBTQIA is frankly nonsensical, and really quite othering, suggesting that the world is divided into straight and non-straight, and that, for example, a young lesbian has more in common with a 50yo trans woman than with a straight woman her own age.
