The use of whataboutisms

 Criticize Jan. 6 - and you get "whatabout" BLM riots.

Criticize Trump - and you get "whatabout" Joe Biden sniffing hair or Hunter Biden's laptop.

Whataboutism is an argumentative tactic where a person or group responds to an accusation or difficult question by deflection. Instead of addressing the point made, they counter it with “but what about X?”.

But let's be honest, we all do it, sometimes subconsciously. Criticize Biden, "whatabout" Trump, or those Christian Fascists, etc. 

So, first question: CAN IT BE a useful tool. Example - to point out hypocrisy? You say this about my guy but your guy does the same thing or worse. Or is there NO excuse for using whataboutisms?

Despite useful advice on how to counter whataboutisms, they usually don't work, or so I've found, but nevertheless, some suggestions found here:

Finally, how about the "ok, let's talk about that" method? If you are talking Trump, and someone tries to whatabout mentioning Joe Biden, say to them "ok, what about Joe Biden? Can you point to something that Joe Biden did that equals what we are talking about concerning Trump?" Or will THAT just lead to a circular argument?  My guy is worse than yours.

That leads to my 2nd question: When confronted with a whataboutism, how do YOU handle it? 

Whatabout you post a meme that is in English?
