The last I knew, most of those races are not uniformly committing crimes against humanity. Most races have a few bad people that ruin it for the whole race, and there are lots of examples of good in most minorities. And to be fair, I will mention that most of them are here, not because they chose to be here, but because religious groups dragged them from their homelands (and their cultures, to which they were optimized) into other lands (which they are not) to serve as slaves against their will. One major incident does not ruin a whole race, yet it serves to incite even worse problems among others.
I prefer to judge a group of people by their actions, not their nationalities and races. Groups of people that continually usurp other lands, trash cultures by invading their homelands and destroying their heirlooms, and then seek to enslave most people by imposing Dark Ages-like mentality on everyone are the ones that do the most damage to humanity. And these groups, regardless of race, are the ones that are reprehensible--not single individuals that do horrible things trashing the reputation of the whole group.
Yes, what happened in Treyvon's case was wrong. However, put in perspective, that is nothing compared to what the Catholic church has done in its history. You hear so much about Treyvon these days--yet, when do you hear about Zionists hijacking the media (the specific individuals that are doing it) and banking system to enslave the whole human race? (And Prison Planet is but one source of information of that rubbish going on.) One incident like that (Rodney King was another one), and it goes on for many months. Yet, people are indifferent to the crusades, torture, and slavery committed in the name of Jesus. We need to put this into perspective--Treyvon is no longer doing anything, and that incident is no longer a direct influence on us. However, ongoing racism stemming from it will only help the globalists and the religions to enslave us all.
