Let's Keep Our Children's Innocence

I've always had something against plays, movies, fiction novels, color War break outs, and anything to do with deception of reality or even getting your mind excited or emotional and spending time on things that are not real. Or making light of everything which the torah calls a leitzon which is one of the 4 kinds who do not receive the shchina. Why not keep kids pure and real at least to an extent? 

I think the whole mindset and social reality of kids is different because of their consistent exposure to all this kind of stuff.

I believe people would be able to advance much more in many important and vital areas if we make an effort to at least limit if not cut off exposure to this kind of thing. 

Have a look at one of the letters of the Alter Rebbe at the end of the old siddur as well as many maamorim of the mitteler rebbe such as hakdama to derech hachaim. There are Maanos from the Rebbe heavily against leitzonus. I think there I urgent work to done in this erena, what do you think?

PS the exception I would give to making light of things which goes in a similar category is when someone is lightening a disagreement or a fight, or the other time when halacha allows is to make fun of avoda Zara, and that includes anything analogous to that.
