"Arrest Mike Pence" is not.
"Put Mike Pence to Trial and then Hang Him" isn't either.
You have to qualify 'Kill That Guy' with something more in order for it not to be calling for someone's murder.
This activity was out in the open, uncontrolled on Parler which is why it was a problem, even if technically it might be legal, Apple doesn't want to deal with that.
I think their response was on point, though Amazon's cancellation has more material effect their responsible response should have been 'you can't go live with that while on our servers you have 3 months to change policy or move out'. Granted, they may have been warned.
The fact that you have to use the phrase ‘kill that guy’ which is a straw man, shows that the logic doesn’t work.
Consider, ‘he should get the electric chair’. It’s pretty clear that this is not a call for assassination.
There is some ambiguity around hanging which is less present with the electric chair, but is not the clear call for assassination you assert it to be.
Agreed, which is why “Hang Mike pence” is not sufficient. On it’s own, it doesn’t make the distinction between two.
If you want to make the case that assassination was being called for, you need to quote something else.
