The New Democratic Party's "Faith and Social Justice Commission" has produced a video to prove that you can be religious and socialist.
My position is that religion should be kept out of politics. There should not be a "Faith and Social Justice Commission" sanctioned by the NDP. (Is there also an "Unfaith and Social Justice Commission" for all those atheists who believe in social justice?)
I have no problem with individuals adhering to one religion or another but keep it personal. There's no need to band together in order to influence policy within the government or even within a party. Frankly I don't care why you support socialist progressive policies as long as you do. Don't try and make it look like religion is what motivates you to favor the left because that just makes you look as silly as the right-wing fundamentalists who use religion to defend their position.
