A favorite argument of 1960s racists to block integrated neighborhoods went like this :

“We can’t say that this particular crime was committed by minorities, but as more minorities move into the neighborhood we predict that these types of crimes will increase – and the neighborhood will eventually become unlivable.”

Sound familiar? Completely irrational thinking and an identical analogy to the claims of climate alarmists about CO2.

No evidence is required. Simply blame the target of your prejudice.
