I find it especially amusing that the same people will argue until their blue in the fact that labels like "demisexual" and "grey-A" are necessary, too. I'm not saying they're not necessary - I do think they're helpful for some people - but you can't make sweeping generalizations about "sexuals" and make it sound like we all have the same level of libido/requirements for sleeping with or being in a relationship with someone, while insisting that there should be a label for every slight difference when it comes to asexuality.
