I am curious why you think that somehow Mr. Romney’s religious freedom would be violated if someone considered his beliefs while deciding whether to vote for him. This sounds like the sort of Orwellian “tolerance” definition the democrats expound to me. If voter X consults his own conscience in deciding how to vote, he violates someone else’s religious freedom? How would Mr. Romney’s freedom to follow his conscience be violated by voter X?
You can do anything you want. If you bring it up on a public forum, you come across as a bigot.
