If you wanna get started here are all instructions: https://kindlemodding.org/ Don’t let it scare you it seems complicated but its just a lot of (easy) steps. So definitely possible in <2h.
You seem to have skipped over actually explaining how this meme is racist… Afaik it’s just one of those exaggerated stretched frames from animation used to animate motion which is why it looks funny. The scene of the cartoon has nothing to do with race, and could just as easily be replaced with any other exaggerated cartoon frame.
If your sole complaint is the addition of the hammer & sickle, then no amount of substituting of bugs bunny with other cartoons will make a difference.
