I dont feel that the Church is really the same oppressive power that it was back in the days of Bakkunin and Marx. Even then, the Church was already on its way out as the dominant political power post enlightenment era, but today the only people who are controlled are those who voluntarily go along with it. I suppose there is a psychological element, but the cure for that is philosophical reason. Out of the big 3 of Capital, Church and State, I think that in much of the world the only significant oppression that remains is from Capital and State. This may be less true in certain parts of the world than it is in the west.

I also dont feel that all religious traditions are equally harmful and oppressive. Quakers, Liberation Theology, Sufi, Zen, Taoism and many indigenous and pagan traditions all have stong libertarian and egalitarian themes to them. Even if they are not based on scientific reason they are not oppressive like the Catholic or Mormon Churches are as armed political organizations.
