not the parent, but the others who responded with "whataboutism". Holding one accountable to the same standards that he holds others accountable isn't wrong. I refuse to take anyone who raises the bogey of "whataboutism" seriously. It has the same validity as someone responding to an argument that it's wrong to make that argument at this time of the day.

Whataboutism isn't pointing out a contradiction or hypocrisy.

It's a method of deflection.

"Whataboutism' is a rhetorical device that involves accusing others of offenses as a way of deflecting attention from one's own deeds."

[josephcsible]

This is the motte-and-bailey fallacy. When people cry whataboutism, it is because the person they're crying it at pointed out their hypocrisy. Then when they get called out on it, they fall back to saying it's a method of deflection.
