...and that's why water is wet!
Well copper isn't wet!
This is a great example of a red herring, or what is often called whataboutisms
It's easy to spot in this example, but is often far more subtle
It's often used to distract from the topic at hand when the person using it has a vested interest in avoiding the original topic
Particularly when dealing with the topic leads to the discomfort of
cognitive dissonance, or when they are engaging disingenuously
No, it's an important topic!
You just don't want to address it
It's not necessarily that the topic isn't a valid one on it's own, it's just that it isn't relevant in this discussion
Simply because one problem may exist, doesn't mean another problem doesn't, or isn't worth fixing until the other is fixed
