I agree, we can't use Barristan's beliefs as fact. He is wrong, or partially wrong, about all of these examples he uses. Based on the WB, the Blackfyre rebellion was primarily the result of Aegon the Unworthy giving his sword to his bastard instead of his heir - not Daemon being in love with Daenerys. At the time of the rebellion, the first Dany had been in Dorne for many years, and had borne her new husband many children. The rebellion had nothing (or very little) to do with her.
Same for the BR/Bittersteel rivalry. It was not just about Shiera, it was about the whole Blackfyre vs Targaryen issue. And Duncan marrying Jenny was not the cause of that war either; it was the combination of all his siblings also refusing their designated matches.
So these statements here are clearly just B's interpretations of history, adding his own motives or perhaps repeating what he heard in songs. I give him no credibility whatsoever on anything he did not witness in person.
