when the legal case in question wasn't really about that at all.
Yes it was - it was about neglect and how the open relationship was a contributory factor to that neglect.
It was unjustifiably conflating poor parenting with non-monogamy
No, it cited precisely how the open relationship these parents had resulted in neglect.
and that to do so was disingenuous, and pejorative towards those who do open relationships of all shades, in an ethical, appropriate, safe and honest way.
No, it didn't say anything like that. That is all fabricated by you. It is not there in the article.
And so yes, I was very offended by it.
You've made yourself offended by words which aren't actually there nor inferred.
OP, do you think there is any connection between your depression and anxiety and your polyamorous choice?
