I'm almost as horrified by this as by some of the Roose crackpairings that always come up in these memes.

I generally don't think that unbalanced power dynamics are necessarily unhealthy or unhappy, so it doesn't bother me all that much. Also, Stannis has very vulnerable sides despite the power he has over other people, and the people he loves will sooner or later find out about those vulnerabilities. Which restores a bit of balance.
