I don’t take calls against political violence as throwing anyone under the bus. He said he was “blindsided”, which I take to mean he didn’t expect him to say what he said. He also:
did not agree with more violence (a good take when it comes to democracy)
recognized Kyle put the whole crew at risk if the tour continued - as this would for sure make it to front page of every right wing hate filled cesspool
I think Kyle said it as more of a joke than serious, but when you don’t know who is in the cult and who isn’t when your looking out at a sea of people at a concert it sounds like Jack made the right call. Getting on a soapbox and “backing” Kyle would would just further put them and their crew in danger.
