my ex is a fan of WWE wrestling. to the extent he actually goes to watch shows. he has our four year old son every weekend and it has become apparent that he has been letting him watch it regularly 
now i hate WWE anyway, i think its absolute shite and personally think that grown adults who watch this kind of rubbish need to grow up and get a life. (ex is a 31 year old man ffs)
i just don't like it because although i know that the violence in it it is staged, i don't want DS watching it as, at 4, he will think it is real. i also worry it might influence DS to try out the moves - as my dear mother said when i asked her about it "that rubbish will just encourage rambunctious behaviour!!" :o
sadly DS thinks the sun shines out of his dads stupid arse and that everything he does or says is really cool
so if daddy thinks wrestling is cool then so will DS.
