A philosphical question and a question of philosophy...

As Christians, we are constantly trying to get rid of those elements of society that function in an immoral manner - porn on the web, violence in video games, sex in TV and movies, etc. My question is for those "free willers" out there, those Armenian brothers:
If God is a God of choice, desiring that individuals chose him, then why do we try to rid an individual of choice? Let me clarify, why do we try to rid ourselves of the negative choices in life?
Do we make for stronger Christians if we remove any possibility of sin?
Do we make for better Christians if we take away any chance of falling away?
Will grace abound? Is our job to clean up society and remove temptations? (I am not talking at a personal level, I am talking at a corporate level).
Someone might well then say, "what choice do we have but to get rid of immoral things, they corrupt, kill, maim and smell bad." Of course they do, they are immoral because they are in direct opposition to the things of God (which tend to smell quite peculiar and tantalizing). But is getting "rid" of this societal corrosion really the answer? Even God left Adam & Eve with a choice, he left them the chance to be immoral. It has always boggled me how much time we Christians put into banning, badmouthing, and breaking down immoral activities only to have five more pop up in their wake. I have long felt that, if anything, we loose ground in this fight. Perhaps, we do not gain ground because our struggle is not meant to be against imoral "things". Perhaps, God has never desired a moral nation or people, but an obedient, loving community. Perhaps, He cares much more about the condition of our souls than the language on our lips (fixing the first will lead to a rebirth in the former).
This is why Christians being involved in the working of politics and schools, homes and businesses, is of the utmost importance, because we must find a way to give a choice to the masses. We must make sure that the world not only has sex, drugs, and rock n' roll to chose from, but that they are able to see and chose the grace that can be found in a relationship with Jesus... If we make clear what is wrong but leave out what is right, we only make for moral people. I am about changed lives, not moral people...
