Our society has never 'suffered' so much physical safety as today. People are so physically safe, that about 40% of the population is comfortable being obese and physically inept.When social justice warriors post on their social media, they incite riots, encourage destruction, and enable violence. Riots like the ones in Ferguson after the death of Mike Brown or the one in Berkeley before the Milo speech have resulted in millions of dollars of property damage and overtime from police departments. This is all verifiable proof.
To answer, arsin in the OP, this is the major threat posed by the SJW; and I do not believe Fool's post, which incited no riots at all, is at all measurable to the SJW post.
iirc, violent crime is down, crime is down. Economic insecurity is way up - and it's this fear that the media and our 'security forces' manipulate masterfully.
But you should read this article about how the Ferguson PD predated a population for their economic gain:
Justice Department's Report on the Ferguson Police Department
Ferguson budgeted for large increases in municipal fines and fees each year, putting pressure on the police and court officials to meet their targets.
As for SJW 'riots' I think the OWS saga is indicative of SJW tactics.
