Of course, one ought not be surprised to see such contemptible rhetoric from Krugman given his history of making numerous preposterous and hateful statements. 

Having no respect for the dead-all 2,977 of them-is hardly the only sin evinced by Krugman today, though. His posting makes no attempt to make an argument and he didn't seem to even bother spell-checking it.

Cowardice is another. It takes a special kind of sociopath to make a hateful remark and then run away when sane people choose to make a response. Why else would he have disabled comments on his post?
