So why is it a sin to vote for Obama, but not a sin to commit genocide (against native Americans), institute slavery (as was done to the blacks), steal other people's lands (from the native Americans and Mexicans), marginalize and ostracize the poor and weak (like what happens to homeless people), infect people's food and water (all those nice GMOs and additives to the water supply), and engage in endless necessary wars which have killed millions mainly for resources (such as oil)?

I believe in god btw, but don't like the way you monopolize him with your rhetoric.
