But Biden or but Trump isn't necessarily wrong if one is admitting both did it and approval or disapproval is equivalent.
My main objection is when one considers the action wrong but justified because the opponent did it. If A is objectively wrong than it is wrong no matter who does it.
Thats the action I have seen lacking in political discussion here on INGO. If I was sitting on the other side of the table from you and we went down the but Biden or but Trump path. One of us should ask is A wrong? If the answer is yes and we agree both did it, we should both agree party B and C where wrong to commit A.
On ingo, when one holds a minority position the guy on the other side who is on the majority changes every 10 minutes.
And when a majority opinion is contradicted by another majority member, the level of scrutiny appears to be at a different level.
This is the correct standard. If both parties agree that the thing is wrong, but one is calling out the hypocrisy of the other, then a "but 'your guy'" statement is admissible. But if it's intended as a justification, then no. Then it just descends into once a wrong has been committed by any side, it's justifiable by the other invoking the right of "but 'your guy'".
