Fantasy, long before forced diversity was preached, was more interesting because the resultant diversity was limitless--anything was possible, yet natural and fluid.
Unfortunately, with forced diversity, now there are restrictions to diversity, to fantasy, to imagination. These diversity advocates put in rules to how diverse or not your characters are. So when you see something out of the norm, you'll be more nonchalant and think "okay so that's the quota used here"; instead of just appreciating the fantasy, the creativity, the uniqueness of characters that go deeper than skin and race. After forced diversity, creators focus too much about tangible, visible, shallow traits.
