(AWoIaF -- "The Targaryen Kings" -- "Daeron II")

The people you refer to who hate Daeron do so because he married off a 15 year old Daenerys to much older Maron Martell to build an alliance with Dorne and bring them into the official fold and under the crown's authority. AND because they believe that DaenerysxDaemon B. had a mutual love for each other, so Daeron separated two lovers. From what is told to us, the impression is that Maron treated her well, if his allowing her to bring critique of Dorne's class divides has any indication (the Gardens). Daemon hadn't been married at this time. And we don't have proof that their feelings was reciprocated or even which side had feelings for each other and which did not, etc. They also had only 2 years between them in age, Daemon and Daenerys.

"It has been said in the years after Daemon Blackfyre proved a traitor that his hatred of Daeron began to grow early."

One, like Fire & Blood, A World of Ice & Fire is, in-world, a historical text written by a maester and its geared towards showing Robert Baratheon & the Lannisters in a more positive light with typical maester/Faith anti magic, xenophobia, & ignorance (sometimes acknowledged) of Essos at certain points.

Two, It's possible that this relationship only exists for a way Daemon's supporters to maintain Daemon's rightfulness towards his legacy, or that they exaggerate. A few of his kids survived, as we know, and would birth/sire people who'd attempt to take the throne.

On the whole, I am like you, prefer to think about and discuss pre-conquest-Dance and the main series and largely because there's dragons and there's more women in the center of the narratives told. I'm the other side of the phenomenon of men losing interest in stories with women centered more; if I see stories with little active or centered women, irdgaf.
