Oh, so you have statistical analysis that social media contributed to a rise in mass shootings by assault weapons? Also, was there not war before? Vietnam? Gulf War? One statistic that isn't up for debate is that 100% of mass shootings with an assault weapon are done with an assault weapon. Whatever you want to say about motivations for carrying out the shootings, they are all done with assault rifles. Lack of access lead to lack of mass shootings with those weapons.
