Sorry to be the semantics guy, but if “asexual” is “non-sexual” wouldn’t “aphobic” and “aspec” mean “non-phobic” and “not on the spectrum” respectively?
Wouldn’t you want to use “acephobic” or something? Like if it were atheism awareness week, I feel like you wouldn’t use “aphobic” again, just because atheist and asexual both have the “a-” prefix.
