Advice on choice of topic

<p>I'm thinking of writing the "Discuss some issue of personal, local, national, or international concern and its importance to you" topic for my commonapp essay. I want to write about bias in the world today, of any kind- gender, colour, religion and so on. Will this be too broad a topic to write on or should I focus on one of the specifics I mentioned above? Also, will it be too controversial a topic to write on? Thanks.</p>
