Nice source. That guy also said this:
Marlon asks readers to engage in an interesting exercise: swap out the “c” in “racist” with a “p”. Ask yourself whether being a non-rapist is enough. Presumably not – you likely describe yourself as being anti-rapist. As such, Marlon argues, you wouldn’t buy an album or vote for someone who is a rapist. The same applies to racism; it’s not enough to not be racist, it’s important to be opposed to racism.
Psychological research clearly demonstrates that, in contemporary Western society, open expressions of prejudice are becoming increasingly rare and are themselves stigmatized (e.g., Hodson, Dovidio, & Gaertner, 2004).
Implying he thinks people who don't actively, consciously prescribe to racism aren't actually racist. This also shows how outdated this article is, even being just 5 years old, since it’s implying that 'open expressions of prejudice' are somehow rare in the year where a sexist, racist, homophobic, xenophobic child molester got elected president, and the guy who legalized gay segregation in 2015 in Indiana is his VP; and that people wouldn't actively vote for a notorious rapist, even though a rape icon is literally the POTUS right now.
But it’s not like elected officials being rapists or prejudiced is new. So I don't really trust him to be socially aware, no matter how academically he may qualify as a source, given he seems completely blind to the issues he claims to be an authority on.
Which is all the more evident, considering:
His article does nothing to cover the entire ace-spectrum (like demi/gray sexuality), so it's not remotely applicable to all cishet aces, because not all cishet aces are "purely" asexual.
He clearly doesn’t take into account the SAM, and is putting a divide between homosexuality and asexuality that doesn’t exist, which is one of my biggest peeves in ace discourse, given that I‘m both gay and ace. He obviously doesn’t understand the effect of romantic orientation on asexuality, and categorizes all asexuals into one big outlier, which tells me he’s likely talking about aromantic asexuals, not every kind of asexual that exists. So this study probably doesn’t even cover cishet aces to begin with.
He uses terms like "either sex", implying there are just the two, which even entry level biologist students know is false.
He uses prejudice and discrimination interchangeably, which is ignorant of the sociological implications of those two terms. Even high school sociology classes will teach you that prejudice and discrimination are different things.
This becomes a problem when he makes claims like “vegetarians are discriminated against”, which implies an institutional oppression of vegetarianism. Which is really funny.
His study was conducted via him basically directly asking conservative, misogynistic republicans "Do you hate asexuality?" and then asking them if they would rent to or hire an asexual person.
He interchangeably uses male and female asexuality, ignoring the complicated social constructs around both, which means his results may be strongly colored by an ignorance of misogyny, rape culture, and its role in asexual women being particularly ostracized - but that is a result of both those things, not of any institutional "aphobia" itself.
And, lastly, he said this:
“Group X” is targeted for its lack of sexual interest even more than homosexuals and bisexuals are targeted for their same-sex interests.
Which, as a gay woman, makes me sick. He only lists housing and employment discrimination (in a study that he himself ran, interviewing extreme conservatives), but that's somehow comparable to capital punishment? Mass murder? Segregation? Imprisonment?
So no. Your source wasn't really worth anything. Kind of weird that you thought an asexual person needed to be educated on her own sexuality by a guy who doesn't even understand the difference between female and male asexuality or the existence of more than two sexes.
Your question is irrelevant because it assumes anyone educated enough to understand that romantic attraction and sexual attraction exist as linked yet distinct concepts would be the person discriminating against a cishet ace. Your source does not distinguish between romantic and sexual orientation or make any effort to define its terms, so its extremely muddy terminology could very well (and most likely does) see "asexual" as inherently "not straight" under the presumption that the asexual person does not experience romantic OR sexual attraction.
I severely doubt Hodson briefed his hyper-conservative polling pool on the difference. He even directly says that only people who don’t know about asexuality very well responded negatively:
Those with more negative attitudes were higher in right-wing authoritarianism, social dominance orientation, sexism, traditional gender-role endorsement, and reported lower previous contact (and less desire for future contact) with asexuals.
Which not only doesn’t validate your point, but contradicts it.
Billy Bob Joe isn't gonna know shit about the split attraction model, so if a cishet demi-ace identifies straight, he's not gonna be like "but you only sleep with people you know personally and trust, you absolute freak". In fact, most Billy Bob Joes will say that's normal, and only react negatively to the introduction of a term for it, because they think it's silly to make words for "normal" things.
Gay aces have to struggle to be accepted as normal. Straight aces have to struggle to be accepted as abnormal. That difference alone should tell you that cishet aces aren't LGBT+.
