Dismantling the relationship hierarchy is not about rearranging it so that sexual and romantic relationships are devalued while QPRs become the new “more than friends.” We need to completely do away with the idea that relationships exist on a fixed hierarchy. Some people will consider friend(s) or a zucchini/QPP the most important part of their life. For some people, their most important relationship will be a sexual relationship (and not necessarily one which includes romance!). And some people will still consider their romantic partner the most important person in their life, and that’s fine too.
Just as it’s harmful to tell an aroace person that romantic and sexual relationships are the most important ones, it’s also harmful to tell an alloaro person that sex is inherently less important than romance or to tell an alloromantic aplatonic person that friendship is inherently more important than romance. There is no way to rank relationships that will not devalue the experiences of at least one group of people, nor is there any reason why we need to rank relationships in the first place.
