I have issues with only men being able to be High Lord, as it just doesn’t make sense as to why magic would be sexist, but if we follow this logic, why would anyone apart form the Night Court give a shit that Feyre is High Lady?
The magic didn’t choose her. It’s just a title that Rhysand gave her. The other High Lords don’t answer to Rhysand. So why should they care?
And let’s say (although I find this nearly impossible to happen) that Rhysand and Feyre disagree on an important political matter, who do the High Lords listen to? Rhysand, chosen by the magic or Feyre, a woman who was given the title by her husband?
“High Lady” is just a title that looks pretty but is ultimately worthless.
