Antifa (i.e. left-wing punks who might try to throw a bottle at your neo-Nazi rally) emerged in the 1980s among skinhead punks with left-wing views. They were usually anarchists. They were like the yin to the "Nazi" skinead yang that was also a thing around the same time.
They went back in history and took that symbol but it's not the same thing as the Communist Party of Germany trying to cobble together some last-ditch alliance against Hitler. That's what that was about in the early 30s. These memes rely on a lot of loose associations, but there's no relationship between the German Communist Party and these antifa groups today. Haaretz is also a liberal Israeli paper that's published in English, but it's not that widely read in Israel.
The German group in that pic BTW with the Israeli flag is a weird and uniquely German phenomenon called Antideutsche. Literally "Antigerman." It's very strange and probably deserves its own thread, but it's comprised of very different people, than a typical antifa group that will try to smash your car if you're in Patriot Front. The Antideutsche people are odd grad students who get really into critical theory like Adorno, are hostile to a lot of far-left anti-imperialist stuff, like Marxists who support Hamas as a "progressive" organization. They published a magazine called Bahamas and they have taken up Israel as a big cause. But it's not a "militant" group.
