Sky News host Chris Kenny says every anti-conservative protest is labelled “peaceful” until it turns violent.

“Now many of the responses to what happened in the US included the sentiment that thankfully it could never happen here,” he said.

“Yep, it has happened here, it was a leftist protest, railing against the new Howard government in 1996 and trying to stop it doing what it was elected to do.

“What a disgraceful and frightening day that was, and so many in the media, and conveniently all the leftist media, had a collective bout of amnesia.”
