There are tons of "hands-on" ways for white men to help. I've known a number of white men from the suburbs who decided to teach in predominately black neighborhoods. Not only that, I also have a buddy who has a medical practice in a predominately black neighborhood. Of course there's also volunteering, supporting neighborhood initiatives, and supporting black businesses.
I think one critical way white men can help the black community is to develop multicultural competencies and become allies. Yes, it's important to have an appreciation for different cultures, but it is even more important to understand the intersections of race, class, and privilege, as well as systems that perpetuate prejudice and exclusion, the impact of learned helplessness, etc. Being "in tune" really helps, and allows one to advocate on issues of social justice...which in the end both includes and extends beyond the black community.
