It’s kind of ridiculous to get mad at that when people are grouped as gay/other or straight anyways. It’s not like you’re forcing the label on nonbinary couples/people who don’t identify with it? If straight cis couples are labeled het, straight trans couples are also labeled het, that’s how words work. Besides, like you said, it would be impossible to find media of it if its not under a label because theres so little and you wouldn’t be about to seek it out without a label to look under... Though honestly some people will just make up an issue with anything or anyone even if there are none
I will check the list out, thanks for your effort for transhet nation
