>Why would somebody, a lot of people, an awful lot, say X is happening if it wasn't?

To push an agenda. Take as an example people that claim that video games are responsible, either partially or wholly, for an increase in violence. There is no definitive link between violent video games and violence, especially as the violent crime rate in the US has been falling for decades now. The people leading this crusade generally do not like games and feel that their disapproval and dislike means that other people shouldn't get to experience them.
