It wasn't any sort of concession, it's something I genuinely have said before in the past and fully maintain. But it's a great and easy way to tear down that these folks don't have any sort of ideological basis beyond identity. They believe that the other side is just as tribalistic as them, that they can win by simply going ah but you believe Obama good. It's the same reason why they believe the murder was justified, not because of any factual basis but because she was 'the other'.

You can see in the other comment that rather than address the actual issue, they instead pivot to an entirely different justification. Because they know their position is truly indefensible and the only way they can win is by continuing to shift the debate. Rather than talk about the extrajudicial murder of an American citizen, you shift the debate to talking about how we need to curb illegal immigration. Because then you can avoid thinking about what happens when Americans are murdered by the state.
