"The Mission has examined documents, publications, statements, Facebook posts and audio-visual materials that have contributed to shaping public opinion on the Rohingya and Muslims more generally. The analysis demonstrates that a carefully crafted hate campaign has developed a negative perception of Muslims among the broad population in Myanmar. This campaign has been the work of a few key players: nationalistic political parties and politicians, leading monks, academics, prominent individuals and members of the Government. This hate campaign, which continues to the present day, portrays the Rohingya and other Muslims as an existential threat to Myanmar and to Buddhism"
I'm not even sure I can take the second point in good faith. Violence having decreased compared to historical high points has literally nothing to say on whether social media itself causes violence. Other factors can easily explain an overall decline, which obviously is not uniform. If you live in one of the countries in which social media is used as a means to instigate genocides, I can tell you that more safety in a US city will matter very little to you.
