As we have seen in the past, it is possible to obtain Megan McArdle's sympathy if she personally sees or has personally experienced your suffering. (See: unemployment.) While avoiding any blogging on the drug pricing scandal, McArdle took the time to (over)write an ode to Syrian refugee suffering.
Her commenters are having none of it. Attracted to McArdle's work by the natural section of their own lack of empathy, they are now informing the little miss that the refugees are just gold-digging proto-terrorists.
You get the commenters you deserve, which is why Roy Edroso's comment section is awesome.
