I'm not a fan either but it's a question of how to depict Israel without it because it's the most recognisable feature of their flag. We even use an adapted version so we're not burning the star here on hexbear.
Very difficult problem for cartoons and symbols really.
Take it up with Israel. If they didn't want the star of david to be seen as a symbol of hate and genocide, then maybe they shouldn't have put it on the flag of a nation that does hate and genocide
