The stereotypical character is definitely unnecessary and bigoted. There is also some truth to what the meme is depicting and what is going on with the current American political parties.

You haven't yet lifted the veil that the joos placed over your eyes fren

Yeah, the stereotypical image of the chariot rider is going too far. However, the meme seems pretty accurate to the political situation in the US right now. Genocide under the Democrats and a continued genocide under the Republicans when Trump ascends to the thrown in November. The state of Israel (through AIPAC and plenty of other organizations) is, by its own admission, purchasing politicians on both "sides of the isle" in order to forward the Jewish supremacy agenda in Israel right now that is resulting in the genocide of Palestinians. It is a terrible situation, but it is not innacurate to call attention to reality and certainly not bigoted, racist or hateful to speak plainly about what is happening in the world. We shouldn't dehumanize anyone, but there is nothing wrong with criticizing people/governments who use vast amounts of money and power in a concerted way to literally push a racist ideology forward. Zionism is a jewish-supremacy ideology and the current leadershipship of Israel is using it to great effect to destroy the Palestinian population.
