Yes, asexual is generally considered part of the LGBT community.
Asexuality, defined as a lack of sexual attraction to others, is often included under the broader LGBTQ+ umbrella. The full acronym (or initialism) can vary, with some including A explicitly (LGBTQIA+) and others implying its inclusion under the "Q" for queer or questioning, or even sometimes under '+' to encompass any identity that isn't cisgender and heterosexual.
Why Asexual Inclusion?
While asexual individuals do not experience sexual attraction, they can still experience romantic attraction, face discrimination based on their orientation, and benefit from the community and support that the LGBTQ+ movement provides. Many asexual people share similar struggles with visibility, acceptance, and understanding as other members of the LGBTQ+ community.
Nuances and Variations
It is important to note that the LGBTQ+ community is diverse, and individual opinions on inclusion can vary. Some within the LGBTQ+ community may debate the inclusion of asexuality because it doesn't involve same-sex attraction. However, the consensus is that asexuality's inclusion acknowledges shared experiences of marginalization and the need for collective advocacy. Furthermore, there are asexual individuals who also identify as lesbian, gay, bisexual, or another sexual orientation, which further strengthens the connection to the broader LGBT community.
Summary
Asexuality is generally accepted and considered part of the LGBT community due to shared experiences of marginalization, the need for community and support, and the overlap between asexuality and other LGBTQ+ identities.
