That is true, but that is not at all what I got from this comment. The context in the meme is someone assuming a jewish steroetype. The comment was contuing that line of false assumptions and connecting it to current affairs. The joke being that mainstream (right wing) media is often replacing "jew" with "zionist" like it's the most normal thing inthe world, while in fact it is not, as you and others have pointed out. The current affair in question is obviously the war in israel.
