Big logical gaps in this argument:

The op never said they were superior morally.

Defining only the horrible acts as horrible is a circular argument as no definition has been provided as horrible.

Other than those three, you really stuck it to the carnist, chief.

You understand the egg in this dish is unfertilized, yes?

They killed a full quarter of their own country. Not in a neglectful kind of way, but full on mass executions, killing fields, concentration camps kind of way.

Pretty comparable, if you ask me.
