For the "yes" crowd it will be because people will have seen more laws being passesd that represent thier own personal views of morality. Never even considering that those laws actually only apply to a relatively small part of the world.
For the "no" crowd it will be the exact opposite of the "yes" crowds first sentence that I just wrote. Second sentence will pretty much stay the same.
For the "don't give a crap" crowd...well they don't give a crap so who cares?
