The topic was about divorced parents. That is why that is the topic. When your response is that the alternative is dysfunctional married parents, then there is something wrong with you. Because everyone else knows that that dysfunctional married are far from the only alternative.
It’s similar to the responses in the threads about appropriate dress for davening. Where the brilliant posters say that “aren’t neat jeans better than dirty ripped dress pants”. It’s not either or.
Same over here.
And who says there aren’t dysfunctional divorced parents? I would say that the likelihood is certainly not lower. And there is as a starting point an incomplete family unit. Which is sad and can have serious impact on the psyche of the children.
