The problem with the current iteration of 'ace awareness' is not the idea of making 'Asexuality' something people are aware of as a possibility, it's the 'Ace-spectrum' which takes the idea of someone not feeling sexual desire (which may be a health issue, or may simply be because they just don't feel it, this is no doubt a minority, but I don't think it has to be a problem) and stretches the meaning beyond all reason into emcompassing all kinds of human relationship interactions and feelings. Lesbian isn't a spectrum. Heterosexual isn't a spectrum. Bisexuality is the only one that could be reasonably argued on a spectrum, but again, it's still going to be a 'yes or no' proposition when it comes to individual attraction.
So, I've got no problem accepting that some people just have no interest in sexual engagement, and that a big shrug of disinterest exists where other people might have a libido. It's when I am told that it is a specific point on the asexuality spectrum to not feel sexual desire until you know someone well, or that you don't feel sexual desire but are perfectly happy to engage in sexual activity and even orgasm, that I become a massive skeptic about it all.
At that stage, you're just describing the wide variety of human sexual behaviour, which is not 'an orientation'. I am a lesbian, and was able to engage in heterosexual activity for many years while feeling no desire. It was psychologically unhealthy human sexual behaviour that I needed to overcome and change, not 'an orientation' that needed a flag and label.
What drives me nuts about all this is that the endless navel-gazing and 'raising awareness' is billed as education, and all it does is muddy the water and mask really unhelpful behaviour. No one should feel pressured or coerced into sexual activity or pairing off. Not a heterosexual woman or man, a bisexual person, a lesbian, a gay man, or a person who has no sexual desire. No extra labels, extensive excuses or communties needed.
We need widespread enthusiastic consent teaching. I see it mentioned sometimes, but I don't think it's actually a thing, and that's pissing me off. My kids and I are constantly referencing the 'cup of tea?' analogy. It's ok to say no because you don't want to and never want to. That's the issue.
