If this issue bothers you, and makes you think about how you might be able to become part of the solution, then I have two books to suggest you read. Both are by Shane Claiborne: "The Irresistible Revolution: Living as an Ordinary Radical"
http://www.amazon.com/Irresistible-R.../dp/0310266300 and "Jesus for President"
http://www.amazon.com/Jesus-Presiden...ref=pd_sim_b_2 They're paperback, so they're not expensive, especially if you buy them second-hand. And they're sure to get you thinking!
Just in case the titles give you pause, consider this definition of the word "radical": Departing markedly from the usual or customary. If you look at these kinds of social issues and are
not thinking "Well, that's not my problem!" or "We have social programs to take care of this" then you may already be a radical!
(Yes it is possible to even be conservative and radical at the same time!)
