It's a shame you feel the way you do.
I wrote something from one man's point of view, which some in the black community could accuse me of being "too white." Thiago's a character I've written plenty about, but he's rarely ventured into controversial issues. My goal was to show how having a son has changed him. So much so, I mentioned Fabricio being a motivation for his action in both scenes.
Racism, something very few of us experience unless our skin color is different, lies at the root of many of the issues you mention. I tried to describe the events in the first section factually, the second was more of way of showing even within the black community there are differences. If we continue to approach everything with preconceived notions and set attitudes, unwilling to place ourselves in someone else's shoes, we're doomed to repeat the errors of the past.
When Obama was elected, one of my mother's best friends made similar arguments to the ones you make. Communists would take over our country the same way they had done to her native Cuba. Guess what, they didn't, and after 8 years we had a peaceful transfer of power. I hope the same happens next time we have a change in the White House.
