The point is that as a society changes, as what’s held sacred and who’s empowered shifts, so do the paths through which evil enters in, the prejudices and blind spots it exploits.
So don’t expect tomorrow’s predators to look like yesterday’s. Don’t expect them to look like the figures your ideology or philosophy or faith would lead you to associate with exploitation.
Expect them, instead, to look like the people whom you yourself would be most likely to respect, most afraid to challenge publicly, or least eager to vilify and hate.
Because your assumptions and pieties are evil’s best opportunity, and your conventional wisdom is what’s most likely to condemn victims to their fate.
That is from Ross Douthat, on the general lessons of Rotherham.
