Africa is a continent, India is a country. The cap isn’t based on diversity, but a country. The reason being the same as several people including myself have stated, namely so that one country doesn’t dominate at the direct expense of all others. Your personal demands based on what you personally want because it would advantage you aren’t how policies anywhere are made.

Given that, and given that your argument is neither consistent nor in good faith, I’m out. It’s clear that you don’t care about diversity or discrimination or anything else, you’re just all about personal advantage. That’s not an argument, it’s a form of bigotry.
