And the sham religious industry probably has a cash flow more than both of those categories combined, and pay no taxes on it, or their real estate holdings. Why is such a travesty allowed? I personally am more annoyed by pushy religious people in my face than by pictures of women.

Your crusade might better be served if you go on a mission to China.
