In many instances, the "A" in "LGBTQIA+" is like the "a" in "logically"—silent. And logically, one would think that all identities in the acronym would be discussed within the community. Unfortunately, asexuality is surrounded by a bubble of silence. While other identities also need more discussion, asexuality is treated differently from even other largely excluded labels. For one, it's not even commonly believed to be real, only that it is a disorder or hormone issue. Inside the community, there are still some who will insist that the "A" stands for "Ally" and only ally, that asexuals don't need to be part of the community because they aren't "truly" oppressed. In fact, many LGBTQ+ individuals feel that asexuals do not belong and that, if they are heteroromantic (romantic attraction to the opposite gender), they are straight and do not deserve to be in it because of straight privilege.
Those people are wrong. While asexuals do not experience the same legal-based discrimination and religious scorn as lesbians and gays do, or the exclusion and ridicule that transgender individuals do in the fight to keep them out of certain bathrooms and steer them away from their preferred gender, asexuals have their own set of issues that negatively impact the person and make it clear they are not largely accepted by society. We are not "straight" in a sexual sense, and although we can generally "pass" and avoid conflict in daily life, it's not the same.
There are many ways in which we can feel isolated, not welcome and not understood by/connected with our peers. For example, a common social response to asexuality is a joke about how asexuals must be plants or reproduce by budding or splitting in two. While the intentions might not be harmful, this normalizes the dehumanization of asexual individuals, showcases the ignorance and the lack of information out there about asexuality aside from high school biology class (which was asexual reproduction, not even asexuality) and implies that without conventional sexuality, someone is stripped of their humanity. Up until last year, not knowing I'm demisexual negatively impacted my interpersonal relationships. It caused a lot of confusion, pain and bad decisions.
