ITA, she never seemed to filter for the sake of his feelings or the kids feelings toward Jon before the split and likely isn't talking nicely about him now.
I don't think you should completely filter everything for your kids. DH and I will make sarcastic comments in front of the kids. Now I will say that I do try to limit anything I say about DH unless we're behind "closed doors" and are having a discussion - then we speak very openly (DH an I).
For those of you who always say "he gave it too," what should he have done after ten + years of her talking to him the way we all saw on TV? When you are immasculated, demeaned, degraded in front of your kids, people at a toy store, the tv audience, the camera crew, friends, etc., what should one do? I don't know. I have never heard a woman talk to her husband the way Kate did, and would be totally humiliated (for him) if I did.
I will be the first to stand up and say I've talked to my DH the way Kate's talked to Jon that I've seen on their show. I can also tell you that it's been, for me, to the point of frustration because I've requested/asked/told him to do something so many times that it's like I have another child. It's 125% frustrating at times. In that respect, I think I know completely how Kate feels. Yes my DH sometimes makes snippy comments back (like Jon) but generally it's an eye roll or attitude in general which ticks me off even more because he won't talk about the "issue" - he blows it off. Not to say I haven't tried to talk to him about these things....it's just the way it is between us right now. For the record, I do have a relationship book on hold at the library to keep me busy during the 15 hour drive to MI on Sunday....maybe that will have some tips for me!
I think if the tables had been turned and we saw Jon talk about Kate's weight, hair loss, inabilities to breath right, put the kids down for a nap, stay where he wanted her while shopping, load the van, etc. People would have yelled "verbal abuse." Can you IMAGINE an episode where Jon encourages solicits, lines up, and takes Kate for cosmetic surgery that she really doesn't seem that keen on?! (Like the hair plugs). People would have gone crazy!
I would love if someone would arrange all of that for me! Just because it was edited to show the person on the receiving end wasn't that interested doesn't mean they weren't. Maybe he was "day dreaming" thinking something like that would "never happen" then when it was available he wasn't so sure? I don't think it's "right" for anyone to constantly berate anyone else - partner or not. Like I said above, I've talked to my DH like Kate's talked to Jon. I've been with guys who were mouthy with me. If you don't speak your mind, they'll continue to do it. Communication is so important.
