The Corpus Christi Movie and Limits to Freedom of Expression

by no name given

To what extent should people be allowed freedom of expression?

I understand the value of freedom of expression and speech etc. but by that same logic, you could suggest that Christians abandon the fight against pornography because people are entitled to view what they want. While this is true, the presence of pornography virtually everywhere is a major temptation to the majority of Christians. Also, consider child pornography. Would you suggest that it is a man's right to freedom of expression when he uploads child pornography?

So the real question is, to what extent do you propose freedom of expression can be practiced?
