This is a really good argument until you learn that mass shooters are less than one in a million but child sexual abusers are more than one in a hundred, despite there being tens of millions of FPS players and probably only hundreds of thousands of CSAM consumers in America. It's a catchy gotcha but it completely fails to hold up under material scrutiny.

Mass shootings and child sexual abuse are very different things, and so are CSAM and video games. You would benefit from losing some of the reductivism you've got there.
