Yes, this is an argument that exists. But it's not supported by evidence. It's the same as the old "video game violence should be outlawed because it might cause real violence", which is just as unsubstantiated.

Yeah, that old canard is ridiculous!

I mean, if there were any truth to it, surely our nation would have seen an uptick, in the past 30–40 years, of new generations picking up guns and just mercilessly mowing down soft targets as if playing GTA.

Thankfully, that is all confined to fantasy in cyberspace!
