Tens of thousands of people joined President Barack Obama and former President George Bush in a peaceful walk across the Edmund Pettus Bridge in Selma, Alabama, today retracing the steps of freedom marchers who fifty years ago began a transformation of the civil rights movement… a transformation which will not be complete until all Americans who have been marginalized because of their sex, their ethnicity, their skin color, their sexual orientation, their physical or mental disability, or their religion are allowed full, unrestricted participation in American civil life.  Joining Presidents Obama and Bush, their wives and President Obama’s daughters, some of the marchers today had been victims of white supremacist brutality fifty years ago at the same place. In spite of Ferguson, Missouri, and Madison, Wisconsin, the nation is acknowledging racism and is getting better. I must believe we are is getting better. The alternative is unacceptable.
