The report itself not only didn't find causation, it did not even find correlation:
"This research does not present even comprehensive descriptive data correlating increased hate speech on social media with increased hate crimes."
"On the other hand, the data from the 2018 regression-model study attempting to examine the effect of social media on bias among its users, specifically focusing on religious bias and racist behavior, did not verify a positive correlation."
"we have found no causal, or even good descriptive correlative data, showing a relationship between video game usage and hate crimes."
"we have found no causal, or even good descriptive correlative data, showing a relationship between hate crimes and chat services."
