How can decent people watch TV?

It disgusts me that there is so much corruption put in front of so many people these days, through TV. , violence, vulgarity, disrespect, disobediance to parents, rebellion, all sorts of immorality, to name a few, are all over tv these days and taught to be ok!! People have no morals these days. Billboards are basicly nowadays...it's sick. Innocence and Purity are made fun of and called immaturity, when in reality they are great virtues. I can't stand it!!! Why can't anyone control themselves?? Why is it that people can blaspheme the name of Christ and feel no remorse? How can people be so promiscuious and not understand it will only bring misery and heartache???
