While I do agree, I also feel the need to point out that this is a meme, it doesn't have any agenda other than "be funny" so probably not much thought has went into it.
It is probably more about recognition, most people (in their minds) don't recognize asexuality. Many folks thought I had something wrong with me (do you know how many erectile dysfunction or micropenis jokes I had to endure?) or I was attracted to them and was trying to hide it.
Why? What compels you to post this?
