I can't pretend to feel gladness over her death, but I am curious/happy to see people discussing the end of the monarchy (in Canada) more in the last week. Maybe it's just popular soundbites and will fade away, but I don't like the idea of the monarchy for many reasons. I'd like to see it end.
That said, QEII was as good a queen as the modern age could hope for. Quiet, apolitical, and accepting of the countries that wished to shrug off the monarchy without putting out statements of authority. She was probably the best the Commonwealth could have got in these decades and who knows if those shoes can be filled.
