You could make a case that based on his other comments and stochastic terrorist language that what he said was dangerous, but those claiming that this specific instance was a threat either didn’t listen closely to what he said (you don’t give someone facing a firing squad a rifle of their own), or just listen to those media reports who are purposefully spreading disinformation.
He has made plenty of statements that are prosecutable, people don’t need to grasp at straws.
To answer the question, yeah if you said the same thing Trump did about Cheney, you’d be fine. It wasn’t a threat. He said give her a rifle and put her on the front lines if she’s so eager to have a war, see how she feels then.
That’s said, Vote. Vote for Harris. While Trump didn’t advocate for putting Cheney in front of a firing squad here, he has asked his military personnel to kill citizens and next time he won’t have someone that will stop him.
But wouldn’t you want the ones who would uproot their lives because Trump was elected? It’s the ones who voted for him that you wouldn’t want. If anything, Canada could use all the non-maga you can get.
