Not really, that's a myth that was never proved, as much they are at odds with the normal yukkuris because of the normal yukkuris being douches on their "highly active not taking it easy nature" so Ayas properly answer their douchebagery, reason why they tend to be more with humans who can appreciate their active nature.
It reminds me the irony of some lovers that would even want Alices and Ayas to be wiped out because they are uneasy, bullies and such against the normal yukkuris, while claiming that even killing a normal yukkuri that is arrogant, shithead, etc. is a bad and horrible thing. . .
Then they wonder why even reasonable lovers hate the PETY types.
Well i did see "Lovers" who did claim that at least only rapists and ayakkuris should be killed, mainly out of the kimmeemaru thing, even though they also include the normal ones out of the "smug" face.
They really left me dumbfounded since that was damn contradicting. . .
