was thinking more along the lines of this study, which shows that "right-wing anti-refugee sentiment on Facebook predicts violent crimes against refugees in municipalities with higher social media usage."
You can't just look at actions by one somewhat arbitrary group against another, and not look at the actions of anyone else, unless you are expressly trying to be misleading.

You can see that the other "group" here, whos actions are deliberately being ignored by the author and everyone else with an agenda, have brought a lot of violence of their own to the table. Or at least have enough conflicting data points to not pretend to "know" something about facebook and framed studies.
"The group represented roughly 2 percent of the German population by end of 2017,[10] but was suspected of committing 8.5 percent of crimes (violations off the German alien law are not included). The numbers suggest that the differences could at least to some extent have to do with the fact that the refugees are younger and more often male than the average German. The statistics show that the asylum-group is highly overrepresented for some types of crime. They account for 14.3 percent of all suspects in crimes against life (which include murder, manslaughter and involuntary manslaughter), 12.2 percent of sexual offences, 11.4 percent of thefts and 9.7 percent of body injuries The report also shows differences between the origin of migrants. Syrians are underrepresented as suspects, whereas citizens from most African countries, especially northern Africans are strongly overerrepresented. Afghans and Pakistanis are particularly overerrepresented in sexual offenses.[7][10]"
