"If we can't get them out, we'll breed them out."
I never understood how that was supposed to make a lick of sense. Nevermind the fact that the whole prima noctis thing is a total fabrication, but how was this supposed to deal with the Scottish nobles? If anything it would have the opposite effect:
1. English nobles would have sexual rights to any *commoner* woman on her wedding night
2. Scottish offspring would legally belong to its parents, but could potentially make ius sanguinis claims to *English* titles.
3. Scottish nobles would be unaffected so long as they didn't marry commoners.
If anything, then, prima noctis would breed the English out. Unless I'm missing something here?
