I apologise, i always thought they were the same thing. Church/religion, state/politics :areyoucra i don't see a difference.
Separation of church and state means that govt cannot favor one religion over another, or favor religion over lack of religion. And that govt cannot prevent people from practicing their religion. It does not mean that religious groups can't get involved in politics.
What religious groups cannot do is endorse a particular party (Dem or Pub) or a particular candidate (McCain or Obama). But they most definitely can weigh in on social issues.
I just dislike that churches (mainly Christian) can wave their magic wands to make their followers approve or crush whatever they want. I guess thats people power for you and religions aren't the only ones who do it. I think i just see religions doing it more than anyone else, mainly Prop 8.
There's a reason why, when Obama wanted to organize people in Chicago to effect change, he went to the churches. Churches already have the structure to do community organizing built into their systems - a large group of people who have a common cause, an effective means of disseminating information, motivation... Yes, it's people power. And yes, churches (and synagogues) do it better than nearly anyone else. But there is nothing stopping non-religious organizations from doing it too.
