And they do tend to get a lot of publicity with it, I'll give them that. But I suspect this has much to do with the fact that journos are often quite far left of the general population themselves. They tend to report on what they sympathize with, and ignore messages and narratives they don't like.
If the MSM were a bit more balanced I'm sure you'd see much less stupid far-left street theatre in the news. And that's because almost all of it is cringeworthy crap. Most punters who have the bad luck to witness it just shake their heads and walk on, thinking "what a bunch of useless tools".
Take this utterly pathetic effort from PETA in Sydney today. It was supposed to turn people off eating at KFC. But if the video itself is any guide, they haven't even made that point clear. (Actually their poor messaging is such a consistent issue that even some of their fellow travellers get annoyed about it!)
Really, I think upon witnessing these bleeding bozos in George St today, most people would have assumed that Andrew Bolt had just lobbed in Sydney, and this was the second trio of Antifa goons he'd clobbered!
