I think the biggest example is the constant use of his office putting forth regulations and promoting legislation that restricts abortion.  True, for Catholics, abortion is evil.  But not all religions feel that way.  To me, restricting access to abortion is a type of religious restriction that maybe shouldn't come from the government.  He also withheld funding to Planned parenthood because one of their clinics in Kansas provides abortion services, even though 95% of what they provide is health care for women.  That is one way he is restricting religious freedom, by forcing his own views on the whole state.    When I see him go to communion, I about throw up in my mouth because he is so horrible in my eyes (personal opinion R & R).    I happen to play the organ at the church he attends most of the time.
