Caring about the case because of the ramifications it may have for people that look like you is fine, but that still doesn't explain why you care so much about how the brother chooses to handle his grief. If you don't agree with he did, there's nothing wrong with expressing that, but some of ya'll are like really up and arms about it as if he did something to personally wrong you.
Tearing down every black person that does something you disagree with is not caring for the community. If that's how black people are committed to treating each other, then we'd all be better off with an "every man for himself" approach to life.
