I definitely never said it was fine… The sad fact is that anyone with any public-facing job gets hate messages and threats all the time. It’s insane, but you have to weigh a message like this against the baseline and make a judgement for yourself. In the majority of cases, blocking this person solves the issue.

The worst thing to do is post about it publicly, because now they know they can contact you. Reach out to people you trust privately, and if you post publicly keep it vague/anonymized.
