It's hard to keep up with the woke grammar nazis.
Well, now that we have legalized homosexual marriage due to the Supreme Court, apparently these 2 are legally married, hence the use of the term “wife”.
I think the term “partner” is used when people are not legally married. And this term is used for both heterosexual and homosexual couples.
You are way behind the curve. That was back when they were pretending to just be nice moderate middle class preppies who liked fixing old houses, telling funny stories, and crying about how they just wish they could visit the person the love in the hospital.
They got gay marriage from that ruse so they don't need it anymore. Now they are free to be who they really are, entitled bullies. So it's all "you WILL bend the knee! We will take your terms and they are no ours! Say one word and you will be de-personned! Now send your kids to a drag show with a bunch of one dollar bills ... or else!"
