Is it really a threat to muse about what could happen as some random person on the internet?
It’s not like OP announced to do it or called for it to be done.
I’d see it differently if a person with a lot of followers (especially crazy ones) would dare to think something like this aloud. Does this law cover former presidents as well?

Anyway… Remember: it’s a losing battle trying to be tolerant of the intolerant!

What if their authority recognizes you?
