Now that you mention it....wow. Such a tragic situation ! The Klingon culture is more intolerant than I realized.
I was not necessarily trying to make a generalized characterization of Klingon culture. I was trying to point out a specific aspect of the story.
Klingon warrior culture considered those Klingons to be dishonorable because they got captured. The warrior code did not tolerate Klingons and their children who became prisoners, even through no fault of their own.
The Klingon government refused to acknowledge them and did not want them back. They were in limbo. Because of their dishonored status in Klingon culture, they chose to stay with the Romulans, even after the Romulans offered them freedom in the beginning.

I don't know how many of the Klingon youngsters were hybrids. Only one was definitely shown to be one. When Worf discovered that one of the girls, Bael, was a hybrid, he was disgusted. Worf's hatred and racism of Romulans personified the general Klingon mindset. She sensed that she would not be accepted in Klingon society.
Even though Bael supported the other young Klingons right to leave, I got the impression that she remained with the community at the end.
It would be tragic if Bael had to just accept cultural norms of intolerance and be stuck in that small community, perhaps the only place, where Klingons and Romulans lived, where she was accepted for who she was.
I don't know if Worf had the guts or honor to fight for Bael's place in Klingon society or if he just passively accepted her outcast fate as a cultural norm.
