Could nursery rhymes affect to childrens behavior?

Yes, One would have to broaden the scope to include so-called Fairy Tales, some Comic Books and tragedy songs, for lack of a better name- there are enough of them on the radio which make light of suicide ( Running Bear, or was it Bare) where two distraught young lovers dive into the local body of water, their tribes fought with each other, so the song goes ( translation race mixing or parents disapprove of friendship) there are whole rafts of very objectional stuff in Disney and other Cartoons. Kids make up some horrific rhymes of there own- including one that made comic light of disposing of an unwanted Baby- (wrap it up in tissue paper- send it down the elevator, First floor stop, second floor stop, third floor, watch the closing doors! and one recalls the case of dead babies tossed down a ventilator shaft in West New York. I don"t know the problem is often analogous to violence on tv and movies but some of this stuff is not for kids. period.
