Since you asked, here are some of the things which some liberals are doing, and I presume even some conservatives are doing to contribute time/money/support:
People in other cities can find out where a vigil is taking place near them by Googling "Justice for Trayvon vigil", and 100 city or your city name. There will reportedly be vigils in over 130 cities.
At the vigil there will be opportunities to find out what other groups and individuals are doing, so that you may find other ways to become more involved.
This Vigil event is being organized by the
National Action Network . Their website has links to other resources related to social justice as well.
Others wanting to do more can contact a local NAACP chapter, or get involved in some other way.
Voting for elected representatives that share your views on civil rights and social justice, and encouraging them to vote for issues which you support is another way to get involved.
As for me personally, I'm active in trying to stop violence in general by promoting peace in many ways. I've been an activist for decades. I've tried to educate myself, spoken publicly, organized/participated in events, written letters, marched, donated lots of time and money, and I've even been arrested for civil disobedience a handful of times.
So what are conservatives doing to stem all of the violence caused by white people? You do know that more murders are committed by white people than any other race in the US, and that the majority (82%) is white on white murder, right?
What are you personally going to do about that?
We are not in some post-racial utopia, and the dystopia we find ourselves in is no accident. I believe that most people whom consider themselves liberal understand that much of the heavy lifting will have to come from within the black community, however it stands to reason that if people are in solidarity instead of active opposition, that the difficult tasks ahead of the black community will be made easier.
Jackson Browne, Eddie Vedder, John Fogarty join Bruce Springsteen to sing Elvis Costello's Peace Love and Understanding:
I feel sad for bitter hateful people that are blinded by prejudice and ignorance, I have better things to do tonight (or so says my better half).
Peace and Love,
