See to me it sounds the opposite, like he's unwilling to bend on anything and expecting her to adapt in each of these instances. And each time she doesn't, he spirals into anger and bad feels. Again, only going off what he's put out there, she hasn't asked him to change his lifestyle or adapt a new way of thinking, or attacked him in any way. Maybe he knows differently, but on its face the shirt thing is really a nonissue. The pronoun thing, she has a friend who changed pronouns. For you and me, that's dumb and not a thing we understand or even care to, but is that what she was demanding of him? I don't think so, from what we were given. His singular focus on this "SJW-ism" issue has led to multi-hour fights with his wife that end with her in tears because, quote, "i said some hurty words."
I'm serious when I said that his feelings are important, if this stuff is that important to him that he's going to the mat over just discussions of SJW-tangential shit where she doesn't come out on his side or reason the way he wants her to, that's fine, that's valid. But the result is that (from what we know) it's turning their house into a miserable place, their marriage into a miserable thing, damaging their relationship, impacting his kid most likely. So... what's the game here? Keep escalating until she becomes the person he wants her to be? Or (more likely) until the relationship is so damaged that it just can't be reconciled and will be contentious forever? You did divorce shit didn't you? You know how this goes. Either he's going to have to come up with some way to have disagreements with her that don't end up in apocalyptic fights or he needs to just get out, otherwise everyone is just going to continue to suffer.
