“Daddy issues” isn’t a kink term, and entirely refers to having a poor relationship with one’s father. I think you mayhe misread their comment as claiming it was a kink term?
The whole disagreement is that they think its lightly misogynistic to say that the only reason to engage in CG/l, or diluted versions of it like calling your partner daddy during sex, is because you had a bad relation with your father. In other words, using the term “daddy issues” at all was the issue, and you doubled down in this comment.
T-Mobile doesn’t even have CGNAT, it’s single-stack IPv6. IPv4 gets routed via NAT64.
