The only context outside of SEP and Deathpigeonx where people who seem to know their shit have taken Stirner seriously is Skye Cleary in her book <em>Existentialism and Romantic Love</em>. Your average man on the street, if convinced that subscribing to egoism as self-government (since the narrower view of egoism as an ought to maximize our own welfare would be another spook to Stirner) doesn't render us murdery and rapey lot, would perhaps be quick to question whether our normal relations of friendship and romantic and familial love could survive under egoism and whether their egoistic replacements. I mean, just think about how people admire Hachikō and not because the dog was in hindsight successful at procuring many tasty treats from strangers.
After reading the book I did saw some appeal in Stirner's views. There are indeed many musts and shoulds about romantic love that our culture conditions in us that are better left unfulfilled; there's a reason why psychotherapists talk about musturbation. But then I also feel like the good parts could be appropriated by some quite a bit less radical view that spares some awkwardness and avoids the connection with the persona of Stirner, since he didn't seem exactly like a great lover based on biography.
