It's worse than childish. The people called out in that bizarre tweet would probably have a conversation with their staff or the police about whether they or their families are in any kind of danger from this apparently popular guy wishing death upon them from the internet, or perhaps from one of his idiot followers.
They might not know much about where Tan is coming from, but they know they work in a building where Moscone and Milk were assassinated.
They would be perfectly reasonable to hire private security and sue Tan for damages to pay for that and whatever other measures that seem prudent for their own protection along with the pain and suffering that goes along with the very reasonable fear this tweet and its effects caused.
What he wrote was more or less the limit to what you can say before it becomes a serious crime.
Agreed. SF politics is profoundly broken, and many of the Supervisors are sclerotic and out of touch. But wishing death on them publicly is very very serious.
I think this modern internet trend of saying that every mistake is inexcusable and should lead to a breakup is super weird and destructive.
What he said was bad, and wrong. But he just needs a scolding and some minor punishment and to then learn and not do it again. If it becomes a pattern then sure, that's a different thing.
This sort of childish behaviour is not just dragging YC down but the startup community as a whole.
