This specific political topic is on the top of everyone's mind. If the US president was assassinated, would you say the same? If your child was killed for political reasons, would you continue your blissful mornings aloof?
This specific political topic is absolutely not the top of everyone's mind. The number of people on HN that this tangibly affects is frankly miniscule.
Most of HN is American. It's on the other side of the world. It has about as much actual effect on the typical American as the just as bad events currently unfolding in Sudan.
