"if the rioters make me late for work I am angry at them,not at the government"Then, you were never on their side, anyway, and it makes no difference who you're angry at.
The protesters are making it very clear who they're angry at, and making it clear they're willing to escalate in the interest of altering the status quo, even if it costs them more than it costs those in power (and it always does). That's what desperation looks like.
I'm personally uncomfortable with the status quo, if the status quo has large segments of people who feel so unheard that they have to riot to get media, to get the attention of those in power, to have any sort of voice at all. Whether I agree with the tactics, or not, I recognize how much this means to so many of my fellow Americans, and I recognize that means there's something really wrong, even if I don't personally feel it in my daily life.
In short: I don't like people getting hurt. I don't like people going to jail. I don't like random acts of destruction. But, even moreso, I don't like my country stepping on the throats of ~13% of the population to maintain the privilege of a few. So, I'm gonna go to the events in my city in solidarity with the folks in Baltimore. Just like I went to the solidarity events for Michael Brown and Eric Garner. And, I'll go to the events for Larry Jackson, an unarmed black man who was gunned down by an Austin police officer, despite having committed no crime (in a rare instance of sanity, the officer has been indicted on a manslaughter charge). I'm a white, middle class, male. I don't necessarily understand all of this...but, I know I can't tell an oppressed person how to respond to their oppression.
