What she said, the now-infamous three words of "hitting the gym", didn't come across as cavalier to me. Just normal FB chatter. And it was in among lots of posts thanking people for help, talking about getting the posters made, talking about handing them out to people, etc. etc.
In the meantime, KH wasn't communicating with anyone on FB about helping out at all. Or saying thank you to anyone at all. Does that mean that KH didn't care because she was doing the "people" communicating? And, as we know by at least one video, when they "hit the gym" they were together.
If I were going to evaluate someone's guilt via FB entries, it wouldn't be TH. Really. Her FB pages showed someone who took care of the kids, was busy, and then was working with people on the search. From KH's, I know he likes heavy metal music and some other stuff, but I didn't see people interaction after Kyron went missing (or much before) and what photos I did see TH had clearly taken.
The only people interaction for KH that I know about for sure, outside of DY & TY, right after Kyron went missing, is his memo to coworkers telling them not to talk to the media and ominously mentioning the company attorney about talking to anyone.
I honestly think the "hitting the gym" and Facebook stuff is over-analyzed, and isn't analyzed fairly and equally. I'm not aiming that at anyone, just a comment on the overall trend.
Or, short form: sauce/goose/gander. If she's wrong for going to the gym, and it indicates lack of concern, ditto for KH. But I don't think going to the gym is an indicator. JMO, of course.
