Why do you suppose hypocrites always tend to hate “whataboutisms”?
When did you stop beating your wife? Since we're asking fallacious questions.
But just in case you sincerely don't understand what's wrong with whataboutisms, it's a deflection. Which means a way to avoid addressing whatever the topic at hand is... by just throwing it back at the other "side."
It's basically what 5 year olds do on the schoolyard playground.
"You're a meanie!"
"But you're a poopyhead!"
"But you're a dumdum!"
and on and on and on and on and on and on and on and on and on.....
without ever addressing any particular topic.
Both sides do it here. All the freakin time.
The fact that you don't see anything wrong with it is amazing to me, and hilarious...but I guess it shouldn't be surprising.
