ok, I read the article and all I have to say is either that person from roto rooter is making it all up, or people there are truly stupid. I can not imagine any adult dumb enough to not realize, once flushed, it is history.
Lets get beyond that. I do not think the makers of the movie are to blame for this, anymore than the makers of the movie where the guy lay down on the yellow line on the highway was to blame for the moron kids that thought they would try it and then died. At some time, you have to draw the line and make people take responsibility for their own actions, and frankly, that includes the parents that buy their kids anything they want, just for the asking, without any thought of consequence. Not just fish, but any type of pet that ends up dead or in animal shelters due to stupidity and neglect.
